if you can afford it - the US has excellent healthcare, you can also get organic food and dare I say better housing, private infra. what the US could/should improve on is have public clinics ie for preventative and quick care. public hospitals in the long run have many problems.
in the U.K for example - I used private healthcare, could've I have to the NHS - yeah but it means waiting times.
the southern states in the US are also what bring the quality of life down.
