I remember some old uncles told me it started with SIA because Oxley Chimp was afraid that SGreans would go on strike and grab him by the balls. A strike by the national airlines could have serious repercussions and so we started employing foreigners as pilots and welcome MCs with open arms for flight attendant positions.
The policy worked like magic and SGreans were thumbed down by Looney, and Oxley Chimp decided to extend the methodology to other areas in our workforce.
It's all about having us under control. If you dare go on strike and sabotage our economy, you could be replaced easily. End up, we didn't even have enough people to go on strike. We were castrated !
Giving PR the chance to own subsidized flat was really stupid, and when SPR started renting out HDB flats, we began to look like the biggest fools in our own country.
