> The money is typically locked away in the country where they're residing. That money can work as investment money.

Investment money isn't as good as money spent for goods. There is limited demand for loans and stocks without a corresponding rise in productivity.

Try making an economy where people don't spend anything and simply save. Or you can save yourself the trouble and see how well that worked out for Japan in the 90's.

> You're also forgetting about the taxes they pay.

Many illegal immigrants don't pay taxes. Immigrants as a whole are paid less (very few are unique geniuses that are paid more), which means that they are actually netting less tax money than if a native was hired. They are also on a lower tax bracket so that is a double whammy.

I really don't see how anyone could be arguing otherwise unless they were trying to exploit H-1B labor themselves.
