I’ve lived in a couple of countries in Europe and some have Universal Healthcare systems (such as the UK and Portugal) but others such as The Netherlands and Germany have Mixed Systems with Health Insurance but highly regulated and were some people can get Health Insurance from the state.

You’re not going to go bankrupt from the treatment or get treatment denied in countries with UHC.

However if you lose your job or never find a job in the first place due to illness related issues or disabilities you’ll almost certainly end up on benefits which again can be better or worse depending in the country.

I would say things have been getting worse all over Europe (personally I think it’s exactly because there’s been too much copying of shit from the US), especially when it comes to the level of benefits for poor people being sufficient (the house prices bubbles all over the place and the lack of building of social housing have made this a massive problem in most countries), but that’s not the same as simply going bankrupt from medical bills because you’ve had an accident, ended up in an emergency ward and got a life saving surgery.
