most may disagree with me, but im just telling you what i see and heard first hand.
the 1Malaysia ideal will not be materialise anytime soon as it is being viewed as a political distraction/propaganda.
and authority(Police/Rela) corruption are on large with the population largely uninformed plus misinformation of the propaganda machine.

Money can still be made tho but i would suggest elsewhere to build a future/family.

[edit]
From the mouth of a foreign friend of mine who have been staying here for almost a decade.
The malays are lazy
The chineses thinks they own everything
The indians lies and lies and lies again.

google it
there's source everywhere
even like the one where a plain-cloth Jakim Authority openly ask for bribe and thrown a racist remarks when they "caught" a chinese/malay couple.

People deriving their income from overseas find living in Msia cheap. The reason for this is probably because of the weak ringgit. When i go back to KL on holidays 20 years ago, this was not very obvious. All my Msian friends who have migrated over to Aust donkey years ago love to go back to Msia nowadays because everything is so cheap!! I don't know much about those working in Spore (Msians) - i am sure they find the same thing too.
