OK, for those who think a bailout shouldn't happen - let's play that scenario out....
People who can't pay their mortgages fall behind, and eventually default. The banks 'lose' on that home, and either hold it or try to sell it for less than it is worth. But, who are they going to sell it to? No one can get credit. Multiply that scenario by hundreds, and the banks fail and the property market implodes.
And then think about the family who defaulted on their mortgage. Their credit is ruined, so they can't buy anything else. They probably also have a great deal of other debt - credit cards maxed out, behind on car payments, perhaps they've taken equity out of their home, etc etc. So, declaring personal bankruptcy becomes likely. Their 'creditors' are then stuck for the debt and must absorb it. Multiply that scenario by many, many thousands.
All of these people who are in financial distress are not buying much more than essentials, so - cars are not being bought, neither are fridges, computers, washing machines, etc. No one is buying furniture or going to restaurants or buying anything but essential clothes/shoes. So retail sales drop dramatically and shops/retail chains begin to go out of business.
With no one to purchase the goods, factories close because there is little need to manufacture anything. Layoffs, redundancies, downsizing, etc, etc etc.
And where are people living? And how are they earning? What do they do and where do they go?
There are MILLIONS of people who may experience the scenario I've described above.
A bailout makes me mad as hell. But it is far better than the alternative.
