We do indeed have better social benefits. But are they really benefits for a SWE in 2021? The social benefits in Europe are great for people with low-mid salaries but as an SWE, I'd rather take a US salary with less social benefits than a European salary.
Benefits for a SWE in the US are probably better so long as you stay one. (My medical benefits are better and cheaper than the universal ones in other countries I’m a citizen of.)
In retirement you might be better too. The US does have a lot of welfare, it’s just mainly targeted at the old and poor.
