As to housing patterns, I’m sure it’s a combination of preference, availability, and affordability. I know Germans from suburbs in Bavaria and Baden-Württemberg and they drive everywhere and enjoy the convenience. These are the same preferences of folks in the US.
As to health care: for people who have decent insurance, you’d be surprised by how nice American healthcare is. When my son had chronic ear infections, in sometimes went down to the pediatricians office multiple times a day. It’s not free at the point of use, but it’s cheap enough where it might as well be. It’s not obviously something that needs fixing.
Again, it’s not like the American left hasn’t been making the pitch for socialized medicine for decades now. At this point Americans probably have an overly rosy picture of European healthcare. They don’t know that French national healthcare has 20% coinsurance, or that many European countries still have insurance companies. It’s just that most voters either have insurance from their employer, and it actually tends to be pretty good, or they have Medicare, which also tends to be pretty good. The fact that some people don’t have that doesn’t motivate the average voter very much, and they don’t want to pay more taxes. Americans don’t have the same sense of solidarity Europeans have, and are much more individualistic.
