 In a society that permits significant income and wealth inequalities, some people will want to buy coverage for these additional services. Why not let them? After all, we allow people to use their after-tax income and wealth as they see fit to pursue the quality of life and opportunities they prefer. The rich can buy special security systems for their homes. They can buy safer cars. They can buy private schooling for their children. Why not allow them to buy supplementary health care for their families?
