> So basically you're making living for locals unaffordable to trade of for tiny amount of taxes from expats and tiny amount of landowner taxes (which are avoided if possible via tax avoidance schemes)?

Living for locals getting expensive is because of higher paying jobs - whether or not it is the immigrants who are helping build those industries - no? What is stopping local realtors building more affordable housing for more people? Imo. these immigrants are just accelerating the process of those industries being built.

And I meant more than just taxes. Expat friends of mine are spending 50-60% of their income in the local economy itself. So even if they are getting taxed at 20-30% lower rate for the first 5 years, they probably spent a lot more than the missing 20-30% taxes to gain the skills needed to move there. Do keep in mind that the employers won't be hiring them and moving them from elsewhere if they are not generating more revenue than they are taking in.
