More or less: the government would out-compete the investors and builders, leaving only those with sustainable business practices left to build the difference (I say this part because a healthy business can (ideally) compete on only the merits, as opposed to trying to cheat the market and hiding costs that way as quite a few do now).

There's a whole ton of asterisks here, and we should probably steal a few ideas from Singapore (not everything, because there are things there that don't apply to here, and vice versa), but it's the general idea.
