I’ll take your word for it.
The problem in both situations is the low birthrate for whites; if not for the Welfare Reform of 1996, this country would be 20%+ black (it brought their birthrate down close to whites by ending “more cash for more kids”). One need only look at the explosion of the Hispanic population to see how much difference the low white birthrate makes; they were projected to surpass blacks in numbers by 2020, but after the 2010 census it appeared that it already happened. Granted, they are constantly reinforced by immigration, but they have more pressing need to breed (both welfare AND anchor babies to remain).
I have zero problem with immigrants who are either skilled or wealthy. Those type do not live on welfare paid by hard working tax payers.
Our current immigration system is NOT based on skill or wealth. It is based on sponsorship by an immigrant relative.
One terrorist from eastern Europe had sponsored 23 relatives for immigration, none of them had to pass any tests for skills, wealth or fluency in English.
By the way New Zealand requires 2/3 of above tests to admit immigrants.
