The only way to end their unhealthy habit, is for you to pay the fines!
Because it would immediately defeat their purpose.
And the PAP's purpose is simply to scare everybody into keeping silent. They do this by frightening critics that they will lose all their possesions.
But if the fines are paid by all citizens, then nobody will lose their possesions. And they may then do what Singapore so desperately needs, speak out when they see wrong.
In addition, citizens who keep having to fork out money to the Lees or Mr.Goh Chok Tong or any other PAP luminary, will be very angry.
And the PAP would not like such public anger focused on them, not when they are carefully pretending to be the good guys.
Alternatively, and to save yourself some money, you could just vote them out!
