If other nations have to pay for the cures they get from Big Pharma research, I suppose it would be too much to ask to quit soaking Americans for the entire cost/expected profits? They will just expect bigger profits, right?
We could say this is a quid pro quo for America’s sake, if these are US based pharma companies. For them to get richer from foreign business isn’t an utter downer for the rest of the USA. Rich entities spend. If I were in business but struggling, I’d prefer richer customers to poorer ones, all else equal.
I think both major parties realize now that if they realistically want more taxes they are going to have to get more spending.
