The winners are the banks, real estate agents, rate collectors, and any investor who realised a capital gain. The losers are people who can't afford their own home. Or people who have bought a home at the expense of becoming a lifetime slave to debt, and any investor who has, or is about to suffer a capital loss (or recoup less than their negative gearing costs). I'd be interested to see some analysis of the numbers of winners and losers, and the extent to which they won or lost.
That being said, government intervention has a tendency to distort markets and the results are almost always negative. That's why you've got to wonder about the future of China, which is a massive economy almost entirely driven by government intervention. *shivers*
