Those people you're referring to already have cash they're sitting on. Once you have enough in the bank that your interest is generating income, you're set for life and can continue amassing all the things at the expense of the poor. It's like a game of Monopoly towards the very end. It's the top few players who own everything, and they're bankrupting the unlucky thimbles who land on Boardwalk.
If you didn't get into the housing market already, I'm sorry but it's not looking good for you if you're not rich. Something drastic needs to happen to put an end to this corrupt system.
