Yes. Which is why the UBI wouldn't make nearly as much difference as people think. Nearly all the "work people don't want to do" is already done by immigrants who won't qualify for UBI (but would still be paying the VAT taxes that fund it).

That's basically how the math works out. Immigrants fund a lot of the UBI by paying into it but not benefiting from it. We would need a lot of protections for non-citizen workers to protect them from being exploited.

To be clear, I'm a big fan of UBI and think it's a great idea, I just worry about the unintended consequences.
