A Chinese dominated government even though they are a minority population? Well....if the communists won, maybe. Then we'd be on the communist side of the Cold War, that'd be interesting. Though I wonder how Singapore, being more of a capitalist sort, would react to this situation. Then again, if the Chinese control the government, we'd not see the split with Singapore.
If though we get a Chinese dominated government that is not communist, like having Lee Kuan Yew winning an election and forming a strong coalition government, then we might see a more bright future for Malaysia as a whole. Though I wonder if some of his iron fisted rules (no chewing gum!) can be practical in a country larger than a city state.
There's also the question of the royal families. Yes, plural, Malaysia has NINE royal families, each with considerable power (currently, PM Mahathir is having a cat fight with the Johor king and his crown prince, with thinly veiled threats on both sides). How would a Chinese dominated government deal with them...by having a Malaysia republic???
Looking at all the things I typed, I wonder if I'm now being monitored by the government hehehehehehe
Also low birth rates by the Chinese, who are much more educated (hence more birth control and family planning) and living in urban areas (with high living costs, hence less kids!) compared to rural Malays who don't care about birth control.
