But this is all else being equal, which is the “lump of labor” fallacy. It’s not obvious that skilled immigrants have the net effect of reducing the wages of non-immigrants with those same skills — tons of new firms are started by skilled immigrants and/or their kids, and the current SV economic expansion particularly so. So, sure. If you already assume that the pie is of fixed size and a skilled immigrant reduces the work available to others, then you can draw the conclusions you do. But otherwise it’s a weak argument.
