GMS is just playing on negative perceptions.
If buying property was truly "slavery", the one will be buying property that would massively deflate in value across time, owners face negative equity, banks will foreclose on the owner, and the ex-owner will homeless, saddled with a debt that they can never repay in their lifetime, work to pay off the debt and with nothing to live on, live on the streets and die out in the cold.
Of course, slavery would be a popular term since prices now are perceived by locals to be higher than usual, but considering how home owners have seen their home values increase through the years, one can one surmise that, and as I have said a long long time ago, Singaporeans should learn how to be investment savvy; Make themselves more knowledgeable in controlling their own finances, stop expecting the government to spoonfeed you all.
One must ask, that if the government did indeed step in and make policies giving Singaporeans an unfair advantage, how long would this advantage last in the open market? Higher HDB cash subsidies would be priced in via bigger demand and therefore less chance of obtaining a flat, building flats faster will suppress asset growth of existing first home owners who plough in their hard earn money into an asset value that remains flat.
The only "slavery" I see are Singaporeans expecting the government to feed them with more. And therein lies the issue, are Singaporeans made "slaves" by the PAP or are they themselves willing slaves to PAP?
Moral of the story: Don't buy that 4D, toto, penny stock, ILP and call it an "investment". Learn to see real opportunity to create an income for yourselves. Learn how to leverage your income and then you will see that you are playing PAP's game for your benefit. Who then is the "slave"?
