Yep this is what a lot of the socialists in the US don't understand - they think you'll get the same level and speed of treatment in EU as the US, you just pay much less.

That is not the case - as mentioned even in pretty serious cases you might need to wait 1 year or more for something that should be done ASAP, on top of that the quality of the doctors isn't the best. This is especially bad for well-off people (as in middle class) as you pay e.g. 500-1000 USD a month and can't even get a basic check-up.
