Nope. Public social spending is low.And yet if you look at social spending per capita, the US would be squarely in the middle rate of western Europe (unless you count private social spending, and then we blow everyone away).
Social spending
Social expenditure comprises cash benefits, direct in-kind provision of goods and services, and tax breaks with social purposes.

Of course the USA has huge private social spending. To sum it up in one word: healthcare. Where due to truly staggering costs, the USA (public and private) spends about twice as much as many Western nations for an inferior average outcome. The nature of private social spending is also inherently the rich spending it plentifully on themselves, and the poor not because they don't have it to spend.
Firstly, precisely how progressive is that? Not very. And what about the less progressive non-federal taxation, because that's still money out of people's pockets? Also, consider that low pay in the USA is incredibly low relatively. The UK has a GDP/capita about 20-30% lower than the USA, but the low end of pay in the UK is actually better than the USA.If you look at federal taxation, the US is more progressively taxed than nearly any other nation on the planet.

That's overreach - too specific. They don't save for emergencies for lots of reasons: because they're too chaotic to plan, or they think they'll deal with problems when they come, or they just prefer to enjoy life in the here and now. Bluntly, probably the main reason they'll be saving more is all the bars, cinemas, restaurants etc. are shut so they've got so many less places to spend.Lots of people in America genuinely don't save for emergencies because they have that much confidence they'll be taken care of.
Bottom end:From what I've seen, actual studies on economic mobility have the US well in line with Europe, pretty much in the middle. At worst, sitting roughly alongside countries like Spain or the UK.

The UK famously sucks on social mobility compared to the West - of course, it's also the Western country closest to the more laissez-faire economic policies of the USA and with high wealth inequality, plus its notorious, lingering class structure.
