FYI, Singapore still has the death penalty for fraud on that scale.
Unfortunately the Mega Churches are on the prowl in packs, but I'm surprised the Singaporeans have allowed them to flourish.
It is a country with the lowest degree in corruption, their students regulary score double-A's at Oxford and Cambridge, poverty there is virtually non-existant, their pension system perhaps the best in the world.
Having lived and worked with Singaporeans many times over the last 6+ decades, the only thing I didn't like about them was their lack of humour.
