They established the Federal Reserve to regulate the nation's money supply and to place controls on the banking activities.<span />

I don't know what "all other" factors could mean - since we don't know what factors have already been mentioned - but I assume that the pay and work conditions would be the same (those could be the "all other" here and the difference is Italy vs Germany/Belgium).
Generally, Italy is not a very likely destination for migrant workers, since it has recently been struggling economically. The payment, working conditions and work stability are likely to be better in Germany or Belgium, so if one can find a job, there, one is more likely to go to Germany or Belgium
The internment of Fred Korematsu was unjustified. Korematsu was one of thousands of Japanese American citizens put into internment camps after the bombing of Pearl Harbor . Korematsu did not commit any crimes nor was he affiliated with the Japanese government at all.
This treatment would not be justified even if he wasn’t a citizen. Unless he committed a crime, his internment / constant surveillance is unjustified.
