Shop-et-al, I may be misunderstanding your post, but the Bipartisan Policy Center (think tank)
has this to say about US immigration policy:
"At a time when soaring national debt threatens economic prosperity, it is important to understand how immigration impacts federal spending and revenues and economic growth.
All immigrants who work in the United States—legally or illegally—impact our national budget outlook, but those impacts differ based on immigration status and other factors. While immigration increases some federal spending, most immigrants are net contributors to the national balance sheet because they pay more in taxes than they claim in benefits:"
In a nutshell, the article goes on to say we won't be able to pay off debt or grow as a nation until we either increase population growth (and we know families are getting smaller) or growth through immigration.
I will repeat myself - maybe we should look at whether US immigration policy is the problem before we start rounding up brown skinned people like cattle and separating families.
