I respect you for a lot of thing you say Walter but this is garbage.
Taxes are not 1000% higher in USA than they are in France or Germany.
The main reason are patents, lack of generics, lacks of leverage of insurers in the American health care system and lack of regulation.
One of the main insulin provider in the USA is currently Sanofi.
Sanofi is a french company.
And the same insulin in France is under 10$ and currently reimbursed at 100% by the government.
Why ? Because in France the health coverage is state managed. And when the state negotiates the prices (paid by tax payers), the industry shut up and accept them.
This is the same in most of Europe Switzerland excepted.
Taxes make up the difference.
