How about a market in organs? Often families are left destitute when the body of the head of household is actually very valuable. It sounds morbid, but everyone benefits and profits from the organ trade except the donor or their family.
It’s stupid that we let non-profits run our blood banks, too. They’re chronically short. A pint of blood runs from $130-350+ depending on region and supplies, yet the FDA prohibits payments for blood. Why? They hate free markets and don’t trust people.
I have always remembered this great article by Walter Williams . There is a shortage of organs because the price is kept at zero by law. Putting a floor on prices (price control) creates shortages. Proven over the centuries, time and time again. How well did Nixon/Carter price control over gas work out?
