Why is it so costly to stay?

Have been calling agents and arrange for flat viewing recently.. and this flat hunting is causing another confusion in my mind.. why is it so costly to survive and stay in singapore?

It's a simple request.. we jus need to small hut for the siblings to stay together lo.. why is it all the sudden soooo many ppl looking for rental flat as well? demand more than supply.. the owner choose the higher offer.. choose the higher qualified tenants.. It has turn into an auction session to close a rental deal now.. gosh..

Can't understand why singapore's properties are so expensive! thought the gov are helping the needy? but can they control the properties cost?? how come the RICH can spend Millions and Millions in CBD Condo? Only Rich can go further Rich.. the middle rage.. jus hang on.. hang on.. hang on..

Money not enough eh... what can be done for the few K that earn every month?
