Absolutely not, most places in Europe outside of a few rich countries like Switzerland and Liechtenstein and maybe a few flagship cities seem very low-QoL compared to similarly sized population centers in the US.
There is also really weird segregation, like neighborhoods where only African-American people live. We once walked into a large restaurant and people looked at us in shock. There were only black people in the restaurant and by the shock on their faces, a family of white people walking in must have been rare occurrence. They were super kind, but it also was very weird.
How many years ago was this? Because over the past 20 years things have gotten better in the US and worse in EU, steadily.
Last time was 15 years ago, though family has been as recent as a few years ago and havent's seen a much of a change change. Also, in many ways, the last 20 years is quite a bad example to pick, since wealth of everyone under the 90th percentile was the same in ~2017-2018 as in ~2007:

Average (and probably 10th percentile) retiree is much richer in US. Yes we have higher variance but the mean is much higher too
Europe also has racial ghettos, it's just different groups
