Earlier quoted context omitted.
There are certainly scales, it's not all uniform. But the EU is a big place and people are free to pick which country they live in. It's disingenuous to suggest it's all the same thing. The larger point of EU workers having more rights is, on average, very true. The US (and China and Russia) treats their workers very poorly by comparison.
> But the EU is a big place and people are free to pick which country they live in. There are limits though. You have a 3 months period where you can stay in another UE country then the national authorities can ask for your leaving. There are statuses that allows you to stay longer (work, studies, retirement, etc.) but those statuses have requirements and obligations. You can't take your tent, set it up somewhere in…
The only 'requirement' is that the government (may) want to see you can provide for yourself in the form of capital, a job, a retirement pension, etc. This is because most countries in the EU have a social safety net, and some have a very strong one. Without this rule the countries with the most generous social security would see mass immigration from rent seekers with no recourse.
The USA doesn't need this rule because it lacks the strong social security.
