How does psoriasis prevalence differ in high-income versus low-income groups, what percentage are affected, and how does healthcare access influence severity?

Hello, this is Mr. Hotsia.

I am 56 years old. I’m writing this from my home in Chiang Rai, in northern Thailand. For 30 of those 56 years, my “job” was to be on the road. My life’s work, as you might know from my YouTube channels ¹, was to travel to every single province of Thailand, Laos, Cambodia, Vietnam, and Myanmar.

My “research method” was living. I ate with the locals. I saw the “ground truth.”

And in 30 years, I’ve seen two different worlds of “sickness.”

The “Old Way” (30 years ago): I sat with 70-year-old grandmothers in remote Lao villages. They were poor (low-income). They were thin. They were strong. Their “sickness” was from a lifetime of work (planting rice). Their “fix” was the real “old way”: nuat phaen boran (traditional Thai massage) and herbs from the market.

The “New Sickness” (Today): I sit in that same village, and the granddaughter is different. She’s overweight. She’s sedentary. Her “food” is “new” (instant noodles, sugary sodas). Her “sickness” is also “new”: diabetes, high blood pressure… and Psoriasis.

Now, I live a second life. I’m a systems analyst by training. Since I retired from government service, I’ve built a career as a professional digital marketer. It’s a job that earned me a ClickBank Platinum Award in 2022.

My new “job” is to sit.

My new “job” is to analyze data. I run over 40 websites, and I research the “high intent keywords” of a US audience. I see what they fear.

And the fear I see in the data is explosive:

“psoriasis won’t go away.”

“why is my skin on fire?”

“psoriasis and stress.”

“can’t afford my biologic.”

My “ground truth” (the new sickness in the village) and my “data” (the fear in the West) have collided.

This is a systems failure.

Psoriasis is not a “skin” problem. It is an autoimmune “engine” failure.

But the sickness—the suffering—is an Economic problem.

As a systems analyst, I had to understand why.

😵 The “System Failure” (The “Accelerant” of “Income”)

First, my “systems analyst” brain.

We must understand the system failure.

Psoriasis is an “engine” (the immune system) that is broken (genetics). It attacks its own “hardware” (the skin).

The “result” is the inflammation (the “fire”) and the scaling (the “symptom”).

But the “engine” (genetics) is not the “problem.”

The problem is the “Accelerant” (the triggers) that “flood” the “broken engine.”

And “Income” (high or low) changes the “accelerant.”

1. The “High-Income” Accelerant (My “Data” – The West)

The “Ground Truth”: This is the Hanoi traffic jam. This is the stress of my “new job” (digital marketing).
The “System”: Mental “accelerant.” Stress. Pressure. Deadlines.
The “Fuel”: “Rich” food. Too much “fuel” (wine, cheese, sugar).
The “Result”: A stressed “engine” + “rich fuel” = a flare-up.

2. The “Low-Income” Accelerant (My “Ground Truth” – The Village)

The “Ground Truth”: This is the “new sickness.”
The “System”: Physical “accelerant.” Stress (money, survival).
The “Fuel”: “Dirty Fuel.” They cannot afford the “old way” (the clean fish/herbs). The only “fuel” they can afford is the “new sickness” (instant noodles, sugary sodas, processed food).
The “Result”: A stressed “engine” + “dirty fuel” = a constant “fire.”

📊 The “Data” (The Real Numbers)

This is the “data analyst” question. What proportion of patients are “affected”?

My “data” (my keyword research) shows the fear is everywhere.

The clinical “data” (the studies I’ve researched for my health sites 2) is blurry… but fascinating.

Globally (Continent vs. Continent):
- My “systems analysis” says prevalence is not “income.” It is geography (genetics).
- The “data” proves this. High-income (like Germany) and low-income (like my Vietnam) have different “prevalence.” It’s genetic.
Nationally (Inside One “System”):
- This is the real “data.”
- The “data” (the US studies) is clear: Psoriasis prevalence is higher in low-income groups.
- The “Percentage”: The “data” shows that up to 40% of psoriasis patients are unemployed or under-employed.
- My “Analysis”: Why? The Vicious Cycle. The “new sickness” (the “dirty fuel” of poverty) is the “accelerant.” The sickness (the shame) stops them from working. The lack of work (the stress) causes the “sickness.”
- It is a trap.

🧑‍⚕️ The “Patch” vs. The “System” (The Severity Fix)

This is the core of the “systems analysis.”

This is how “access” influences “severity”.

1. The “High-Income” Fix (My “Data” – The West)

The “Access”: Total. They can see the “systems analyst” (the doctor).
The “Fix”: The “Patch.” The “new way.”
The “Tool”: Creams (the “patch”). Pills (the “patch”). Biologics (the expensive “patch”).
The “Severity” (The Outcome): Low. The “patch” works. It stops the “fire.”
The “Problem”:Details: The “patch” (the drug) has side effects (my keywords show the fear). And it does not fix the “accelerant” (the stress).

2. The “Low-Income” Fix (My “Ground Truth” – The Village)

The “Access”: Zero. The “doctor” is 100km away.
The “Fix”: The “Old Way.”
The “Tool”: Herbs from the market. Stillness (the monk’s “fix”).
The “Severity” (The Outcome): Catastrophic.
The “Problem” (The Systems Failure): The “old way” (herbs) cannot “fix” a genetic “engine” failure (autoimmune) that is being flooded by the “accelerant” (the stress) and “dirty fuel” (the processed food).
The “fire” burns out of control. The “severity” is 1000 times worse.

📊 Table 1: Mr. Hotsia’s “Systems Log” (The “Economic” Failure)

As a systems analyst, I log the data.

The “System” (The Group)	The “Accelerant” (The “Ground Truth”)	The “Fix” (The “Access”)	My “Hotsia” Verdict (The “Severity”)
High-Income (My “Data”)	“Stress.” (The “Hanoi Traffic” / My new job).	High. (The “Patch” – Pills / Biologics).	Low. (The symptom is managed).
Low-Income (My “Ground Truth”)	“Dirty Fuel.” (The “New Sickness” / Stress).	Zero. (The “Old Way” only).	Catastrophic. (The “fire” burns uncontrolled).

📊 Table 2: The “Traveler’s” vs. “Data” Toolkit (The “Fixes”)

Here is my “field guide” as both a traveler and an analyst.

The “Fix” (The “Tool”)	The “Mechanism” (The “Data”)	The “Target” (The “System”)	My “Hotsia” Verdict (The “So What?”)
The “Patch” (Biologics)	“Fire Extinguisher” (Stops the “fire”)	The Symptom (The Fire)	The “Rich” Fix. (It works. But it is not a “fix”).
The “Old Way” (Herbs)	“Coolant” (Anti-inflammatory)	The Symptom (The Fire)	The “Poor” Fix. (It is “ground truth,” but too weak).
The “Old Way” (Stress Fix)	“Calm” (Meditation/Yoga)	The Root Cause (The “Accelerant”)	The “Smart” Fix. (The only “fix” both “systems” can use).
The “Old Way” (Food)	“Clean Fuel” (No “New Sickness”)	The Root Cause (The “Accelerant”)	*The Real* “Fix.** (The hardest “fix” for both “systems”).

🌏 A Traveler’s Final Word: The “System” is the “Ground Truth”

I am 56 years old. I must keep moving (my travels). But my new job (my ClickBank work) forces me to sit.

My body is “ground zero” for this “systems failure.”

My “ground truth” (the village) and my “data” (the keywords) are the same.

The “data” is undeniable:

Psoriasis is not a “skin” problem. It is a “systems failure.”
But the suffering is not “medical.” It is economic.

The “High-Income” (my data) buys the “patch” (the biologic) to stop the “symptom”… but lives with the “accelerant” (the stress).

The “Low-Income” (my ground truth) lives with the “symptom”… because they cannot “buy” the “patch”… and they cannot “afford” the “clean fuel.”

The real “sickness” is the “system” that links “health” to “money.”

🙋‍♂️ My Research FAQ (Frequently Asked Questions)

1. Is “Psoriasis” caused by “Poverty”?

My “systems analyst” answer: No. The “engine failure” (autoimmune) is genetic. The “Poverty” (low-income) is the “Accelerator.” It is the “dirty fuel” (bad food) and the “panic” (stress) at the same time. It makes the “fire” worse.

2. Is it “worse” in the “West” (High-Income)?

My “ground truth” (traveler) answer: The “Prevalence” (the number) is higher… but the “Severity” (the suffering) is lower. Why? Access. They have access to the “patch.” In the “village,” I have seen the “ground truth” of “no access.” It is catastrophic.

3. I’m “low-income.” What is the “Hotsia” fix?

My “systems analyst” and “traveler” answer:

“Clean the Fuel.” This is the #1 “fix”. Stop the “new sickness.” Stop the sugar. Stop the soda. This is cheap. This stops the “accelerant.”
Use the “Old Way.” Walk (my “traveler’s” fix). Breathe (the “monk’s” fix). This fixes the stress.
This is the “system” you can control.

4. What about the “new sickness” (processed food)?

My “ground truth” answer: This is the “enemy.” I see it. My Kaphrao Sajai (real food) 3 is better “fuel” than the instant noodle. The “new sickness” is the “dirty fuel.”

5. Mr. Hotsia, what’s your “ground truth” fix?

My “ground truth”? I’m 56. My “systems” (travel and sitting) are both “stress.”

I eat the “old way” (my Kaphrao Sajai – which has herbs).
I move (my travels).
I respect the “data” (the studies)… and the “data” proves the “old way” (the calm) is the “smarter system.”
