Just want to list down all those "things" in Singapore for which prices can be pushed up until all disposable income and savings of common people are eliminated (assuming they stay in Singapore).
1) accommodation (no choice, or leave)
2) education (you want to stay - you can send your chiild abroad, but for yourself - no choice)
3) transportation (still 20x40 kilometers, can't just walk)
4) alcohol/tobacco (taxes)
5) utilities
...please, somebody help me continue the list or prove me being wrong

I did not put food and clothing in that list since those can be easily imported.
