Sinkies credit PAP for our NS system, which created ASEAN's most potent fighting force that has kept sinkies safe for the past 52 years. The decision to conscript sinkies was a painful decision costing PAP lots of political capital. Luckily, sinkies were rational voters who were not easily swayed by the populist speeches made by the marxists and the leftists.
CPF is another idea credited to the PAP. CPF stands out in recent years, especially when we see pension plans in the PIIGS country run out of cash or sponsored by taking on more debt. CPF money earns you a good compounded interest of around 5% per year. You will get a huge retirement sum if you start early. I maxed out my special account years ago. Today, I feel very rich looking at my CPF account.
