singapore also depends largely on natural wealth,indirectly
the island placed the largest oil refining facilities that produced more than million barrels of refined oil for different grade--of course largely of thoese experts managing those facilities are actualt expat from europe & US(naturally this has been the case since decades since SIngapore also is the main port & British HQ  managing the resource from this regin since even before WW1)
while currently our facilities not even half of that output
wait till the pengerang facilities completed & the game will change & large part of their revenues will lost there
also when they island already virtually saturated to the max,their businesses & population slowly already moved into JB/Nusajaya-which indirectly making our country being flooded by their economic progress,indirectly
