How is the current system of house ownership working out for the vast majority of people.

Some people have no chance of ever owning anything, some people are underwater on houses that now have bigger mortgages than the house is worth, some people are still making due, and the upper groups of owners own so many properties that the prices will never go down unless the economy crashes and everyone loses.

Getting more people in coops and other non market housing is a good idea and I don't see any actual ideas from the other parties that don't just enrich those who already have too much.
