In my country (the Netherlands) there is help for expats to settle. Getting a job, house, etc. There's even a tax cut for expats if you have a specialized job. Denmark might have something similar, I'm not sure. Their language is a pain to learn though (not like my language is fun lol). But like the Dutch the Danish are very good with English, especially in cities. Getting a job while only speaking English is not a problem. Denmark is a beautiful and amazing country, with amazing people. But we have bitterballen.

Europe. With benefits, decent holidays, no limited number of sick days, can't get fired without a proper reason (or you can sue them with a high probability of getting compensation or getting your job back). In Sweden the standard work week is 32 hours. In the Netherlands 36 but many do 32. Here in NL we have extra holiday money and often a 13th month payout. Irregular shifts have bonuses and extra time off, and aren't allowed to be too long shifts. Not that all jobs are decent, but at least the law protects employees and many employers want employees to stay, so they are treated properly. There are also tax cuts for the first job you have, it just doesn't apply to other jobs if you have multiple. And you build up a pension if you're not self employed. I'd like to see the minimum wage to be raised, and equal in the entire EU. So there's definitely room for improvement. But compared to the US it's heaven.
