Don't be sour grapes lah.
I have relatives in places like Australia, Canada,... they live in bungalows. Some homes even have swimming pools. They usually have 2 cars. Some even take public transport to work because it is cheap & reliable. They are living the middle class lifestyle.
They have to pay high income tax but it is not a zero sum game. In return the children get free education, everyone gets affordable comprehensive medical insurance, unemployment, ... etc They sometimes complain about the high taxes but interestingly none have returned to Spore
You can't blame the ex-Sporeans for looking for greener pastures. If you want someone to blame, blame the PAP for NS, cronyism, high hidden taxes, depressing the wages, making things so expensive,...
