Government determined to increase population to 7 mil in 2030.

[HitandRun]

The governement's solution is to increase the population through immigrants. No doubt, the increase in populatioin will lead to larger supply of goods/services, but do not forget, this same group of people will lead to a corresponding demand of goods/servces. Moreover, with limited land supply in singapore, wont these larger group of immigrants inflate property prices further and raise COE higher? (you get more inflation now)

The assumption is that the working population tends to create a surplus of goods and services, which is pretty logical to me. Does the average person save most of his money while he is working or retired?

Whoops. I think I misunderstood your question. With a larger group of immigrants, it is possible for property prices and COE prices to go up. If we can control the pace well, perhaps it (the inflation) would be moderated if we could slowly ramp up the supply of property and COE.
