Will you explain why these exact things have only had precisely the opposite effects in practice?

Seems like flawed theory to me.

Considering immigrants (as well as most low-wage Americans) primarily purchase cheap imported goods, the only jobs we appear to be creating by this method are extreme low-wage jobs, just like I said. Any other revenue goes to very wealthy who stash it or invest in capital or property, which makes it harder for most Americans to own a home.
