Circumcized Penis are easier to clean. That law from the God of Abraham was because bathing was not a daily event when in the desert.
Uncircumcized needs daily cleaning under the foreskin to prevent infections, etc/
I know large families of Jewish people who live in my area. Why they rise to great heights is the lifestyle. Family, God and education is their culture.
They are very intelligent people. Education is everything to them. They often subsidize family member's education and give them $$$ to open businesses..
They help each other and generally live beneath their means.
Thus they rise to the top in many fields because of this..but when a scapegoat is needed, Jews are the first to be blamed merely because of their success.
Great people. They help one another to succeed. They excel which is why they rise to powerful positions, thus are often cited as a problem.. They earn their positions.
Other nations hate them because of their success.
Are there bad Jews? Of course, just as their are bad Americans, blacks, and people of any ethnicity..
Evil can be found in ALL groups. So can good.
