And it has greatly improved British teeth. The old stereotype of bad British teeth was because of how things were before the NHS. My English father's teeth were so bad that he ended up having to go to Costa Rica to get the surgery done because it would have cost $10,000 in the U.S. out of pocket. He was born in 1931, so the NHS didn't even exist until he was 17, but he always considered it the greatest accomplishment that Britain had achieved (my father was also a die-hard socialist who bragged about how he booed Churchill when Churchill visited his high school). He'd be pretty appalled at the state of it now.
