The objections to all of these phenomena are really not what people say they are.
The theory is we should protect people from themselves.
If you were really concerned about expenditures on entitlements, you would take people whose families have lived here for a very long time and weren’t being economically productive and you would deport them.
There are also outliers like me who would choose to have female children or gay children and would balance things out.
The people who waved their American flags and shout about patriotism and at the same time don’t want immigrants to come across our borders or are concerned about illegal immigrants have missed the entire point of America.
