Oh, John, do you want to start a war between the 4 countries? *lol*
Phil --> worst in economy amongst the 4 (I'm not accusing, official report said so). Democracy is quite existing, as protests are allowed on the street. Native-born really look similar with Malay race (Indonesian/Malaysian). Have many typhoon cyclones as their regular natural disaster.
Thai--> military junta to love and to hate. No democracy, of course, due to the coup. The people worship the King, so don't you dare to say bad things about His Majesty. Bangkok traffic is the worst of the worst in Southeast Asia.
Malas--> as you can see from their nickname: Malas, means Lazy. Badly need immigrant workers to do simple or low-level jobs, but at the same time treating them like s**t. No democracy, protest not allowed, media controlled by the govt. Applied segregacy policy between major races. Ruled by authoritarian party who's leader luckily resign at his best time before toppled like the Indonesian authoritarian. Desperately want to be the top tourist destination: they send 2 of their best terrorists to bomb a beautiful neighbouring country, so the tourist flock in to Malaysia instead. Lack of creative people, decided to hijack a neighbouring country's folk song for their tourism ad campaign. Establish a civilian militia corps who are being given the rights to raid, detain, arrest, without proper warrant (they rob and rape as well), of those who they THINK are illegal immigrants.
Indonesia --> diligent and hardest workers amongst the 4, although seldom not punctual. Located in the deadly ring-of-fire, lots of earthquakes and mount erruption as the regular natural disaster. Democracy is getting better and better after toppling down the authoritarian in '98. The most populous amongst the 4, therefore is not easy to handle 1001 problems at the same time.
