Your comment is premised on the notion that immigration vs. locals is a zero-sum game. It is not uniformly so.

Restrictionists claim: "If fewer Mexicans, Indians, and Chinese came to the US, then American citizens would be better off."

There frankly isn't compelling evidence that this will happen. The number of immigrants using up social services is minuscule and the amount of tax coming from 100s of thousands of H1Bs (and illegals/undocumenteds) is all going into social services used by veterans, American seniors, etc.

On top of this, because immigrants are usually the cream of their own societies and/or have taken big risks coming to the US, themselves and their children contribute via starting new businesses, etc.

This notion that immigration is part of a zero-sum game is likely flawed.
