I agree with the both but would add: about half of the hospitals disappear and elderly care takes off (or else, voluntary euthanasia becomes legal).

Cigarettes and Tanning take off. A bunch of health and nutrition pseudo scientists disappear.

Chemical industry takes off due to government contracts, to create an illness to force people to use hospitals and allow for more money to flow back to the gov

If it's free, then lots of predatory pharma and insurance companies are, thankfully, finished with making money off of folks with cancer wanting to not die.

A cure for all cancers is developed(It's free). What industries take off amd what industries die?
