I think a lot of you guys from the US don't really get how high the taxes are here that pay for this stuff, especially for people that make more than the average.
If you would work non-contract here in Poland for an equivalent of ~$120k you would pay around $1k USD. If your wife is working she will also pay, of course this also covers all you kids.
So lets say both of you make around $120k here - so you would pay $2k monthly for "free" healthcare and its quality is atrocious. Even for serious stuff you many times need to wait 1-2 years for something, all hospitals are understaffed, the care quality is abysmal.
If you are ambitious and make good money the US is better. Europe in general is better for people that don't aim too high and want the state to enforce some minimum of QoL for them at the expense of the rest.
