You're welcome to walk to the cafe on the other side of town... however, if you're in a larger city in the southwest, you can expect that walk to take several hours. Just driving from one edge of the Phoenix metro area to the other corner can take upwards of over an hour and a half, and our traffic isn't nearly as bad as other cities.

As for healthcare... that's a mixed bag... you can go to the ER and you will be treated, but the bill afterwards may or may not be impactful... There have been some improvements, but the healthcare lobby is massive, and pretty much stops most reasonable and some unreasonable improvements.

On public transportation, it varies... you need to realize that the main part of the US is by itself about the size of Europe... I would assume there are plenty of areas of Europe where public transit is likely limited. Not even getting into Alaska, which is by itself massive and largely unpopulated. It's probably better to compare individual US States to EU nations in terms of transit.
