You will see a lot of buying power from free health care providers as they represent tens-hundreds of millions of people - they will most likely pass on a price gouging drug in favour for others. They won't pay market rate, whatever the drug manufacturers say.

VC backed companies will sell you private health insurance as a perk. It is rarely useful.

99% of the world lives far below anything you consider average.
For a website full of smart people, you all have trouble recognising your own extreme privledge.
