Given poor people are more dependent on welfare and social security (having no plan B, like wealthy folks do), they should be the ones most in favor of population (and therefore economic) growth.
Illegal immigrants aren't getting social security either, but are paying into sales tax.
Which means they're doing their part to support 30% of state budgets, in addition to the businesses they're working for who are paying their own taxes.
That if the economy craters, because suddenly population growth isn't buttressed by immigration (legal or illegal), then both social security and welfare rapidly become unfundable, and the poor suffer more than billionaires.
Ergo, poor people should be in favor of any sort of immigration.
