You don't want the government to own all the houses, all the shops, banks or theatres,
why not? the high street of the town I live in is dead, council meetings (minutes published online) show that the reason for this is that rent is too high, and that private landlords won't bring down rents, it's been a battle over many years of the council trying to improve the town centre where they can, but work going to waste because nobody can afford to rent retail units.
If the Local government owned the stock they could at least see problems and set the market rates accordingly.
Having a controlling figure in the rental market would help stop speculation.
Having an entirely free market approach to houses has led to runaway house prices,
this has the affect that only those extremely well of, very credit worth of investor groups can afford to buy houses.
and meant that the rental market has "boomed" - read those too poor to be approved for a mortgage get told that they couldn't possibly afford the minimum repayments, and that therefore they must go rent a place (at a price that's higher than the mortgage would have been!
when you think about it, if rental prices could be controlled or reduced, then less people would struggle, less people would be in debt, less people would need housing benefits, the benefits cost could therefore be better distributed.
(i.e it could be giving someone a reliable car rather than lining the pockets of an investment group that bought houses.)
those that appear to be saving a probably in as much debt, if not more than you.
whilst that may be possible, I can say that you could not service the minimum payments as well as rent, council tax, gas/electric water as well as food and anything else. (let alone have anything left to save!)
