Quite a few people state that medical breakthroughs will dry up without a profit margin but I wonder if this is true. Does anyone have any statistics on major medical breakthroughs that were happened upon simply because of love of money vs. ones that came about through dedication and love of the medical craft? I understand that companies like to patent their drugs, etc. and so pay researchers to research. But isn't it possible that these discoveries would happen anyway. And is it possible that many shortcuts get taken with an eye to the bottom line (I'm thinking of drugs that come on the market that turn out to have deadly side effects)?
