To speculate, there is a belief in alt-med circles that the formal health care system is much more concerned with how to monetize healthcare rather than make people healthier. They believe that simple, “natural” methods and treatments are far better than manufactured drugs.
They talk about conventional medicine as “allopathic”, and assert doctors would rather treat chronic conditions than cure them or prevent them. Because chronic conditions mean repeat visits for “routine followups” and medications mean drug companies make regular income rather than a one-time cure.
There may be something legitimate in how the system is primed. Once your start seeing a specialist, do they ever say “you don’t need to come back?” Or is it always “see you in 6 months.”
But it’s mostly a charicature of health care and health providers. Doctors works be thrilled to find actual cures for diseases. Antibiotics is curative.
Doctors also discuss overall health and illness prevention, including losing weight, improving diet, cutting smoking, limiting drinking, healthy lifestyle choices, the works.
But guess what - too many people are unwilling to make all the recommended changes. And some notions of healthy diet may have bad underlying assumptions, data, or science.
And even if you do all that right, there are things that happen due to aging, or genetics, or other factors.
The alt med holistic medicine types want to believe there’s a magical way to live that is healthy, that special treatments or practices will enhance your health without side effects, And that if we all just did all that, the majority of our chronic diseases quid disappear.
While the majority of us could do some things better and reduce the incidence of things like heart disease, there are still problems we face that won’t go away with wishful thinking.
So to bring it back to the quote, the “illness industrial complex” is the traditional diet and health care industry that focuses on keeping us sick so it can keep treating us, and the chronic diseases are the result of the industry’s focus on treatment, not cures or prevention.
