Oz is an island-continent, Thailand, Malaysia are countries with land. Singapore is a small island. Land is limited. (Haven't you noticed?) Land allocation has to be prioritised with consideration for different uses. You want land here for people to plant kang-kong? Use your brains will you?
I am on E (Employment) Pass here. Because of my "Foreigner" status, my employer does not need to make CPF contributions for me. Hence I do not have CPF. I have medical insurance for hospital needs, if needed. You wish to call this BULL, that's up to you, but it is the truth.
Cheers!
