In 2001 there were 200,000 knee replacements which was a category of health care that didn't exist what, 25 years ago, 20 years ago. To complain that our healthcare system is too expensive and therefore people are suffering when in fact causation runs the other direction because people have so much access to healthcare it's driving up the price. Much rather that society be spending money on making people healthier and alleviating their suffering than all the other ways we could spend money.
