The great thing about America is that there isn't a one size fits all answer to your question, each state offers something different. In general I'd split the American people in two in regards to culture, there are the Northeastern/West Coast Americans which make up half of the population, and then there are the Southern and Western Americans which make up the other half. Those in the Northeast and West coast tend to be more politically left wing, socially liberal, less religious, more diverse.
Southern and Western America is mostly right wing politically, socially conservative, quite religious, mostly white with a growing latino population. Southern/Western Americans tend to be more polite and easy going but less welcoming to diversity, Northeastern/West Coast Americans have the reputation of being perhaps a bit cold to other people in regards to manners, but more tolerant of differences. I currently live in the Northeast, but my attitudes are more akin with those living in the South/West and I plan to move out west one day for a variety of reasons, mainly because it is very expensive to live in the urbanized American north east.
The cost of living is extremely high in the North East and West Coast, where as in the South and West with the population spread farther out you can afford much more in terms of land and housing for much less. Taxes depends on a variety of factors, if you live in blue states (states that tend to vote Democrat or left wing) these states usually have higher taxes. New York state (blue state) has the highest taxes in the country.
Red states (states that vote republican or right wing) usually have very low taxes, some red states don't tax your income at all. Taxes will also depend on what sort of property you own, but the same rings true, property taxes in blue states, specifically ones with high populations are higher than in red states even if those red states have the same population or more. This is the case because as mentioned above, the South and West are right wing and the people living there don't stand for high taxation, this also means less government services but they aren't keen on such things anyway.
On the contrary those in the Northeast and on the West coast are more left wing and they support entitlements and government services so their taxes are much higher. There is of course basic federal income tax that goes to the federal government that is not dependent on where you live, but the changeable aspect of your taxes would be from state and local location. You'll also probably notice quickly there is a tremendous cultural difference between America and the rest of the Western world.
For one, Americans love guns; it's common place to people have guns in the home, even military type weapons like assault rifles. You are even allowed to carry guns around with you with certain permits, this might be the cause of alarm in other countries but it is normal in America and part of the culture. I wouldn't fear gun crime though, most gun crimes that are not personal in nature occur in "wrong place wrong time" fashion in city environments with bad reputations.
All in all where you want to live is your choice, it will depend on the type of people you want to be around, how economically advantageous it is to live in certain areas, and just what you happen to like geographically speaking.
I went to live with my family over in America for a while (currently live in Somerset south west England ) and although America does have advantages (namely the best cereal in the world lucky charms which you can't get in England) but I do just like Britan because although jobs are few here and America is considered 'the land of opportunity' I think the general attitude of people are better ( I'm not suggest that Americans have bad attitudes) and the few jobs really depends on what you can do if you are wanting a very specific job like 'Video game designer' (I realise very few people who read this will be looking for a job in designing video games) then it is sort of hard not to find work, I just really am proud to be British and love my country and although America was a really cool place to live I enjoy living in England. In America it did feel like people did sort of have a bit more of a relaxed style about things which can be good or bad depending on your perspective they also have a more open feel towards religion in most parts, I know this from when my cousin came to stay here and was a Christian and was shocked by the amount of people who just weren't interested in religion and thought it was and old persons story ( her words not mine).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
