The foreign trash in London are even worse than the trash in Singapore. They certainly aren't tourists. They're there for good. ....black HIV infected refugees, Gypsies and other Eastern European garbage, Arab scum, Paki muslim fanatics who preach hatred under the guise of freedom of expression.
The suburbs of the big cities aren't homogenous. While the rich can take refuge in the upper class neighborhoods, the poor suburbs are just as bad as the inner city slums.
