well we cannot put down each races like that, at least individually each race does contribute in some areas to the progress of the economy...and what areas are these:
Malays - Ah Mat (drivers), drug addicts (without them you think our police jiak simi), footballers (if not how our Ass Lick survive).
India - Drunks (boost biz for Tiger Beer our home grown brand), Wives beaters (Counselors and lawyers for divorce case).
Chinese - Ah Longs (Very helpful when the IR starts), Gamblers (if not Singapore Pool go bust), GL cheongsters (hehehe I am one of them and as a result Singapore tourism boom due to many prc mei coming).
See regardless of race language or religion we all played a part in the progress of this nation.
