Cost inflation isn't unique to the United States.
Europe isn't a single country.
> yet the lifestyle of European citizens in those countries is much better than the lifestyle of the poorest Americans
Does this include the Romani people? Does this include the Ukranians being attacked by Russia?
Greece's housing cost burden is higher than 30 US states. Not all regions in the USA have faced serious property cost pressures. [1] [2]
"Day to day stuff" is a very broad category, and that includes items that are flat or decreasing in cost. In that sense I will point out that VAT is much higher in the EU than sales tax in most US states, with VAT rates of >20% being very common while the highest combined sales tax in the USA is just over 10%. Sales tax/VAT is a very regressive tax that harms the poor the most. For someone on the poor end of the spectrum in Europe, buying something like a computer or television is a greater burden than someone in the US.
I'm reminded of the natural gas price spikes in 2022 in Europe, and of how the EU's average electricity price is about 2-3x higher than it is in the US. The US has an extremely stable supply of basic needs like energy and food.
Education costs have been flat or lower than the rate of inflation in the US since roughly 2016, so for the last 10 years the idea that education is becoming more expensive in the USA has been squarely false. [3]
Healthcare, I'll give you that one, the US is not faring well. But we can look at some systems in Europe having their own difficulties like the UK and Spain and it's not like healthcare isn't a challenge elsewhere. I will also point out that the US does have public healthcare for the poorest (Medicaid) and for all people over 65 years old (Medicare), and Medicare is a standout in quality among public healthcare systems in some outcome categories.

Most of Europe has lower GDP per capita than the poorest states of the US, yet the lifestyle of European citizens in those countries is much better than the lifestyle of the poorest Americans. American growth is built on the backs of piss-poor healthcare, shoddy education and an overinflated perception of the tech sector which holds the rest of the world hostage (but not for long).
