@Rich,
Basic laws of economics, not pie-in-the-sky ideology, dictate
that industrialized nations, for instance the US, Germany, Sweden,
Great Britain and so forth, rely on imported labor from historically
cheaper-wage societies, repugnant as such may seem to countries
with traditionally tight-knit, homogeneous backgrounds!
If present-day Germany or the US derived their labor costs SOLELY from a
homegrown, Caucasian, Christian workforce, nowadays, no German or American
citizen could afford much of anything.
This was not so, say, seventy-five or a hundred years ago across the board. However,
in the case of the US, the Immigration Act of 1925 ensured the stoppage of immigrants
from Sicily, Spain, the Philippines which even then provided a cheap labor force for goods
made in the United States.
