There are plenty of cultures outside of the US where owning property and a house is a sign of affluence and is a lifetime dream for some people. Having to own a car on top of that is just gravy.
For people that don't want to drive, there isn't much I can do to convince you. You might be better off in Paris, London, or even Vancouver than the US. (maybe NYC, if you can find an affordable place to live)
Healthcare covers your partner and your children. It may or may not cover your elderly parents depending on which company and which state.
There are regions other than Europe. There's South America, Central America, East Asia, India, ...
There's probably a reason why immigration to the US from Western Europe is small and the annual quotas aren't usually met, while the quotas for India are usually met by February. My guess is that Europe is already a nice place, and it's more of a lateral move for Europeans to work in the US.
Cost of living in the US is generally lower than in EU. There are certainly regions where it is high, but the same could be said about Europe. (I could afford Poland better than I could afford France)
There are lots of reasons not to want to move to the USA.
I agree with you there. But plenty of folks find reasons to go forward with it anyways. Even with the horrible painful paperwork for a visa.
