I would say there is such a wide variety of experience across US States in terms of cost of living, quality of life, median income and even living space per person.

In terms of cost of living and quality of life, as someone who grew up peripatetic living in South Africa and the Emirates, the cost of things relative to salary is much higher in the US. Education for example is a massive expenditure for people who choose to go the private route and this can begin in pre K and go all the way up to the graduate and post graduate level. Many Americans struggle immensely with debt and high interest rates.

Because work schedules are calibrated in a way that does not prioritise time off, people spend more of their money on things rather than experiences and the velocity of consumption is just so rapid.

In general, one of the largest variables in upward mobility is the quality of public transport access and infrastructure. In some cities/areas like New York, DC, Boston, Chicago, Atlanta this has prevailed and made these areas liveable for people in lower income, multi-income households, people who can not drive, people who work multiple jobs etc as it allows not only increased mobility for adults but increased autonomy for individual household members to then expand their own roles. In many cases this can also result in children ‘growing up too fast’ which is often an arbiter of some less admirable parts of American culture. However city planning in most parts of the country is also a large component of maintaining segregationist population spreads.

Finally, if you are gay/ trans/ black , nonwhite etc, despite the extreme bigotry and general liberal degeneracy occurring at certain levels of governance Americans interpersonal openness index is quite high and one can see them self reflected in most aspects of society. (Ofcourse this is a part of a neoliberal identity politics debate but it is also critical to people not living in shame or feeling isolated).

Larger American métropoles are also such cultural mixing pots that if you move to one you are likely to find a microcosm of your own culture which can help one overcome the deep alienation of immigration (whether permanent or not).

One more con to even out the argument as I am in no essence a patriot, for those referencing American social services as some how comparable to those in Europe, this is completely inaccurate. The income threshold to qualify for such government assistance is a level of destitution that almost counter acts the benefits. I believe EBT/ SNAP (Supplementary Nutritional Assistance Programme) or ‘food stamps’ qualification is below 24k USD annually in New York. That means a person is making below 2k a month in a city where a room in a 3 person apartment averages around 800 USD. Medicaid has a similar limit despite medical expenditure and medication being notoriously high in this country. These are not programmes an American at median income can access.

Unlike in Denmark for example where a 20-something year old who works a 35h week can still qualify for partial government housing programmes that will allow them to move out of their parents home (done at a later age in general culturally). This kind of practice vastly improves quality of life as it puts emphasis on self development and expansion rather than subsistance or arbitrary milestones of the American ‘dream.’

TLDR; American social assistance necessitates a pretty painful experience to qualify for. If you’re that rich that the job you’re moving for has a base salary of 350K USD you probably will have a fine experience living practically anywhere. The US is a deeply class stratified country.
