The basic problem of going from renting to owning has been going on for generations, and in the geographical regions where people want to live - no surprise - it is worst.
In the late '60's my brother in Los Angeles asked my dad for help with a down payment on his first house, and my dad declined because he said he didn't want to put himself in a position where all five of us would be coming to him for similar help; he simply did not have that much to spread around (he was living in my house at the time, which he did until he died in 1991).
Two years later, the house that my brother was looking at had increased in value by 50%, and he was even further away from that elusive down payment.
Economists tell us that the explosion in rental costs is simply a matter of supply and demand. In places like San Francisco, local "green space" requirements and zoning restrictions - as well as geographical limits - severely constrain the creation of new rental units, so that rents skyrocket. Rent stabilization laws cause landlords to scale back on property maintenance, creating shit-hole apartments that are featured in newsreels from time to time.
The best the government can do for rents is to get the hell out of the way of utilizing existing space and new development. In Pittsburgh, where I live, the City owns thousands of vacant properties that could be bought, renovated, and brought back on to the tax roles EASILY, but regulations, zoning restrictions, and an entrenched bureaucracy keeps them vacant and deteriorating. Any new apartment buildings have to have a significant percentage of "affordable" units, a requirement that scares away any rational developers, and limits activity to those who are willing to play the various games and exploit all the available give-aways. Hence, new housing developments are extremely rare as complaints about high rents proliferate.
