Demand driven problem.
Information is readily available.
Most people already know what to do.

Way I see it:
People don't want to be "healthy" because it takes effort.

Most doctors and medical professionals do care about other people's health. Politicians and corporate leadership only care about profits and these are the people who can help push big trends.

And here we are..
Small minority who eat, exercise and live with few health problems.
Rest get sick and rely on health care to keep them alive/healthy.
