Cannot find a more bigoted version of it elsewhere of the Internet.

You do know said immigrants tend to work illegally or for subhuman wages, pooling their wealth and network in local societies? They also tend to immigrate not to rural our crime-laden parts of the US.

On the other hand, US poor are nuclear and in places with few perspectives. They might be saddled with debt, a problem which the immigrants do not have. (Medical, educational or housing.) Therefore helping them establish local communities might be the first step, but it is not enough most of the time. There have to be actual opportunities to be had.

It is easier to start with nothing in a good place, than with less than nothing in squalor.
