If it hadn't been for Salk refusing personal profit? Bidness doesn't do anything it can't make money on. It always cracks me up to hear the euphemisms in "Vision Statements" and the like. The only reason any business exists is to make money for the shareholders. Think the government doesn't already fund the majority of drug research? Think again. Google "university drug discoveries" some time. Lilly spends roughly 17 dollars on advertising for every dollar it spends on research. Take government grants to universities out of drug research and see what happens.
There are some things the government does that it is uniquely qualified to do. Pure research is one of them. In bidness, you better be damned sure you're going to discover something the shareholders are going to be able to make money on in 10 months. Or you can forget the company paying for your research. We're about to learn a painful lesson about that now that the Big O has decided to "privatize" NASA. Sit back and watch how well that works. Most big discoveries come serendipitously. Bidness won't stand for that, but researchers at universities - with government grants - do it every day.
Making a buck is not the only motivation for most people. And personally, I don't want anyone who is driven exclusively by the pursuit of profit making decisions about my healthcare. It should be obvious why, but I'll elaborate: for such a person given the choice between greater profit for them or better health for me, I will lose 100% of the time.
