Interesting question. As I read through the thread I see a lot of explanations on why it happened rather than where the money went. Heck, it gives everyone a chance to vent their own political agenda. Kinda fun. But it doesn’t really address the question.
Let’s look at a typical person making $1,000 week ($52K annually). Owns a home (with a mortgage) and hasn’t lost thier job. Net worth is a composition of all you own and rightly or wrongly, we tend to gear our spending on how much we have and how much we have left after the bills are paid. If this guy hasn’t lost his job nor taken a pay cut, he should not be any worse off, right? Not quite.
Say you had a typical small SUV, getting 20mpg. Before all this started you were paying about $1200/yr ($100/mo) for gas. At the peak of the recession you were paying $2400/yr ($200/mo) where did that money go, Saudi Arabia. Right now you are paying about $1800/yr. The Saudis are doing quite well. So that’s a piece. Also, since you are paying more for gas, you may want a more economical car. Unfortunately your car is worth less because of the mileage, so your trade in has less value, anywhere from a few hundred to a few thousand in trade in value. Where did that money go? It simply evaporated. There’s no question it was real money when you bought the car but the value is no longer there.
It doesn’t stop there. Say your house was worth $200,000. Now it’s worth $160,000 (a 30% decline). Also say you were a responsible citizen and bought it with 20% down. Your 20% ($40,000) is gone. Where did it go? The evil bank didn’t take it, hell their losing money as well. It was real when you bought the house but it’s gone, evaporated. To make the problem worse the bank now has to scramble to come up with the difference in thier asset base.
Let’s say the bank has one depositor and one borrower. The deposit was $160,000, the same $160,000 you borrowed to buy the house. The bank had the asset (mortgage on your house) with plenty of room to spare (house was worth $200,000. Now however, the need to come up with an additional $20,000 just to cover their deposits. Once again it was real when it was deposited and real when you borrowed it. Now it’s gone, evaporated.
This is how some of the banks went bankrupt. Their revenue didn’t change, their expenses didn’t change, but the value of thier assets went down and they could no longer cover the deposits. Bankrupt!
So back to our guy making $52,000/yr. He’s paying more for gas, less income. He may be paying more on a car loan to compensate but again less income. He now has a mortgage that’s under water so he feels broke and has lost $40,000 in real money. He no longer has an asset to borrow against if things go bad, so he’s trying to save a little, less spending. With less spending comes a reduction in goods and services, maybe he’ll fix that old dryer instead of replacing it. Consequently fewer jobs. the only people that made out were the Saudis, the rest just evaporated.
It’s a bit more complex than this and yes derivatives and play a part in making it worse but the general concept is valid.
