In the US, for a black to become a president is a HUGE achievement because the whole system, since slavery, is organized against blacks.

Turnoi: Every system in the US, since slavery which made the US prosperous, is focused on the black people. Example: Remove Obamacare so the white people won't have to pay for dozens of millions of black people. Housing policies still maintain black people in some areas and not in others. The Electoral College, which elected trump although he got almost 2.865 million votes less than Hillary, was designed at the end of the 18th century to give additional votes to states with black slaves against large states like New York which were against slavery. Voter registration (mostly in the south). Police force. The confederate flag. etc etc.

You don't have anything like that in Europe since the Nazis, so I understand that you can't understand easily.
