Separately, in a way we already have that uneven net for the same work. If you work two jobs you get paid less (net) than one person doing either of your jobs (for that job, not total). That's what's what a progressive tax does.
Its a market distortion that could create all kinds of problems.
You could argue that's discrimination( there are equal pay and equal wages laws around employment).
You would not be allowing immigrants from doing a wide range of jobs that are desirable (and hence pay less) and 'condemn' them to do the worse jobs that pay more. So for example, immigrants will be less represented in arts, journalism, administrative work. Low paying jobs in general will not be living wages without UBI. Think that minimum wage is likely to drop considerable if you have UBI.
It undoubtedly creates an "US vs them" gap measurable in money.

UBI is very likely not going to apply to most workers, maybe minimum wage and down. You dont really need much of a minimum wage if you have an UBI, which means many pleasent low skill jobs would pay very little (clerical work for example). So immigrants would be barred from such jobs without UBI.
Also its true that taxes make 2 people get different net income but that comes from their wealth, not their nationality. Someone with a house and a mortgage might get more income than an immigrant that has nothing. That makes it a regressive tax (the immigrant pays taxes that goes to the richer guy).
