Either 2011 March or June-Oct is General Election, so have to
give out ang pows (prosperous money) to buy votes. 
Why will the less skilled and poor get more money during
GE2011?
It's because they are less skilled makes little money, so
if you give them some money they will be easily swayed by your
money.
Let vote for PAP so that we can get an ang pow once every 5
years. But then be prepared to pay more for GST, fines, ERP, PUB
and HDB for 4 years. 
Why vote PAP? 
PAP give you the money but you can still screw them and vote
opposition. 
You vote PAP, after election they take back the money and much
more from you.
You vote opposition, PAP after election they take back the
money and much more from you.
Vote opposition so that PAP will spend more time "fixing"
them and not much time to take back your money.
