Universal health care is not EU wide. Quite a few countries do not have that. Bulgaria sits at 15% uninsured for example. PTO is nice, but it is really just a way of paying out money. In the end it hardly matters. If you earn more on the days you work, then it ends up being roughly the same. Mutual assistance is very very loose. Plenty of EU countries have no problem whatsortever to send refugees to die. Homelessness is much more common in the EU then in the US.

At the same time the EU has with Hungary a full blown dictatorship. Far right governments are ruling multiple member states already and are systematically removing workers rights. Greece just introduced the 6 day work week and eliminated a lot of worker protections as well.
