If any state could be called apartheid (or at least proudly and institutionally segregationist) it seems to me that uMNO ruled Malaysia is it.
I do not agree with this. While there are laws in Malaysia, which I totally oppose, that enforces economic privileges for Bumiputra (sons of the soil which is just non-Chinese and non-Indians) as well as making it illegal to question these laws, there are no laws that enforces segregation. Any racial or religious segregation are of the auto-segregation type. These laws exist due to the economic domination of the Chinese and to some extent Indians in the Malaysia private sector which co-exist with Malay political domination. I would more compare this system to USA affirmative action laws and Indian caste base reservation system than South Africa. It does not make it oppose it any less but it is not a fair comparison.
Just like in USA and India the economic impact these attempts of economic distribution had fairly low level of impact in shifting the economic hierarchy of the various groups involved after the first few years of the system being put in place. As expected the elite of the beneficiary groups tended to hog most if not all the benefits and the overall economic balance of power between the advanced economic groups and backward economic groups have not changed.
