Dubai's tax gets mentioned on social media posts regularly and it's the home of a couple of prominent Reform fans. I was there a few weeks ago and there are a few other things about it that could be relevant to this thread.
First and foremost, the vast majority of people there are immigrants, around 80%. And there's a very broad mix of people and cultures. Westerners can drink and go to the beach - within reason. But it is baseline Islamic. Immigration workers at the airport don't wear a uniform as such and hand you a sim card for the duration of your stay. From then on the whole immigration system works on face recognition and you don't need to see a human. But, of course, that's not the result of liberal democracy. It's a federal authoritarian monarchy with a terrible record on human rights. Basically Singapore in the Middle East. And the facial recognition, while convenient, is also Orwellian.
When I was going @hart's shirt was good enough to provide me with extensive and excellent visitor info, which was immensely kind and I really liked the place. I like particularly how people rub along no matter where they're from. But I wouldn't want to get on the wrong side of the government.
My suspicion is, with Reform, that they quite fancy the authoritarian control and tax position but I think achieving it by having 80% of the population as immigrants would give most of their voters a coronary.
There are two entirely differing worlds for foreigners settling there.
