Agreed. Nobody takes into account the total loss of social security in the US. Healthcare, retirement, child aid, education, .... If anything, I'd be upset if I were living in the US about other jobs not earning at least that much, to make ends meet, particularly given the huge risks everyone has to shoulder on their own.
In the UK my wife and I loose 25-30% of our pay checks to tax and national insurance and I would imagine the cost of living in the UK is comparable to the US. Our household income is considered pretty high in the UK as well so it’s not that we are badly paid in UK terms
At least here in the Netherlands the minimal, obligatory package is about 100 euros a month. this is with 375 of own risk (doesn't include doctors visits). This package will basically make sure you'll never get a real surprise, except when you have something with your teeth, oddly. Some cheap drugs are not covered. And for example there are sometimes discussions of whether new immuno-oncology related drugs that go well over 100.000 a year per patient will be in this package.
For people with low income there is "zorgtoeslag", they get sponsoring from the government.
In the UK you get everything for free regardless of work history or other factors. Every prescription has a £12 charge, topping out at a maximum of about £150 a year. Dental treatments are also normally charged at a low rate.
