I think marketers and the whole machinery of business in general push people to solve symptoms rather than problems.

Symptoms are easy to cover up or solve quickly and changing them / covering them up often requires little or no fundamental change in lifestyle. Plus if you keep the person's fundamental flaws in place then you ensure demand for a subscription for your half solution.

People are also willing to pay a premium to shift blame. That drug did not help me. That diet does not work.

Who has more money to spend on marketing? The person who can fix an embarrassing problem by suggesting fundamental life changes that cause the change, or a person selling a half assed mask that paints over symptoms and requires the equivalent of a subscription to maintain.

I sometimes think this way about many psychotropic drugs on the market, and many marketing tools, but I also think this about being overweight. Me being overweight is not really the problem, but it is a symptom of an unbalanced sedentary lifestyle coupled with poor diet.

The value of good life changing advice is hard to put a price on, and perhaps that is part of the reason it is typically so cheap in cost relative to bogus quick fixes and scam subscriptions.
