Why is it that Malaysians look down on Indonesians?

Question

The same thing that Singaporeans look down on Malaysians?

Answer 1

 cultural grudge? when malaysia was founded, indonesia our "older" brother nation had been independent a little bit longer then us. while we finally achieved independents PEACEFULLY from the british they were unreasonably angry. we dont know why la. this led to some armed conflict and even indonesian attacked on the penisula and even in singapore. so even today even though it is history people still feel the grudge. just like the British feel for the Germans, the grudge is still there. its normal la.
