If I see "paid vacation" as an argument for why life in europe is better one more time, when an american doing the same job could take half the year off and still have more money left over, I'm gonna have an aneurysm.

Well, you have to get hired the next year, which is not easy and not instant either. And after doing this a few times (leave after half year), no one will hire you.

Then there is this “little” problem of heath insurance. There are like other gothchas too.

If what you said would be feasible, lots of folks would do it. But the reality shows otherwise.
