people are driven by self-interest.
a lot of votes for the PAP are driven by fear. it may not reflect the true will of the people. and now they suffer the consequences of our low productivity economy which will suffer greatly in the months to come. in a high productivity economy, blue collar jobs pay well. if we had this, there will be more than sufficient jobs for all Singaporeans.
people tend to follow the herd, it's nature. if enough of the herd break off and walk their own path, eventually the rest of the herd will join them. that's what the hardcore 30% opposition have been hoping for, to get enough of the herd to break track and walk a different path.
