The Geithner Housing Bailout plan has only highlighted what is essentially true about any form of government intervention in the markets – that there are winners & losers, and its basically fair/unfair depending on which group you belong.
But there is one universal truth to the effectiveness of such plans, and it is that they should be simple and easy to understand. One of the major benefits of a market system is its transparency and easy to understand signals (high price = sell, low price = buy, if you don’t value something at $500, don’t buy it at $500). So any assistance program with complicated rules (like the Geithner plan) is bound to fail with many people not taking advantage of it, and it will empower the middle-men (loan brokers) who have the financial incentive to interpret the rules and find loop holes.
This is precisely how the whole derivatives mess happened in the first place, with the financial instruments being too complicated even for execs to understand, and the middle men (Wall Street quant jocks & loan brokers) making decisions that enriched them, but collectively took the economy down with them.
So my suggestion would be that the government should step into the market, but with more clear rules – they should set up a Resolution Trust Co. to just buy the houses that are about to go into foreclosure, and then rent them back out to the occupants on a long term lease.
This would be similar to how a government take over of a bank or auto company might look like, where the government ponies up the cash and keeps the employees (occupants) and factories (house) , but wipes out the equity holder and basically takes over.
The rent can be determined by market rates in the area, and the government can bascially sign itself a contract to own the houses until the housing prices in the area stabilize (or rise above a certain threshold), which would then stabilize housing prices because all these foreclosed homes would have a government guaranteed floor price.
