For me you could sum up whether a country is decent to live in for me on a few factors .
1. Countries where the majority of the population is religious, religion is a harbinger for division and prejudice, and why is its always people with a sh. it life who praise god
2 Countries where inequality is massive
3. Countries without a welfare state or support network
USA is dreadful on all counts.
Having worked in Texas briefly , i was surprised by the depravation, some areas the housing is appalling far worse than any thing in the UK. Like other posters I was also surprised by the number of people who drink and drive. Although the US speak the same language as us(almost) i think we have more in common with our European neighbours
