It's not basic supply and demand--indeed, most economists are pro immigration. Bryan Caplan went as far as advocating for open border (admittedly he's more libertarian than most).
Labor market is complicated because jobs are not a finite pool that people compete over. New workers are also new consumers, who create new jobs as well. If more workers are always bad for other workers, declining birth rate (ie fewer future workers) would be a good thing.

New workers with much lower purchasing power will not be consuming as much/as well. Heck, a lot of companies are known to hand out directions on how to get food stamps upon hiring (i think Walmart was one of the notable cases).
Without proper rights may get new consumers but you may also get more pressure on the welfare system (which is already weak in the US).

You skip the part where declining birth rate is a very strong in developed countries but not as strong (in some cases, not strong at all) in not-equally developed countries.
