Saudi Arabia have the closest thing to an UBI and Saudi nationals notorious for having bad work ethics and low skills. The economy is pretty much run by foreign workers. The country will be completely doomed if it continues this path and the oil runs out. The government is trying all kind of policies to prevent this.

This is a bad example with many compounding factors, not just the one variable being UBI. There are many differences between Saudi culture and ours here in the US, many differences in the way in this proposed, etc. Also important to note that this essentially applies to men of Saudi decent only. It is not UBI, it's missing the U.
