In order to do math with lots of zeros drop the zero's. 700 billion is 700,000 million divide by 300 million you can drop the millions. that leaves 700,000/300 now drop two zero's from each side and you get 7000/3. Remember we are working with dollars here. and 3 zero's equals 1 thousand. so 7 thousand dollars for every 3 people or 2333.33 for each person.
That being said the problem is that money has no value at all. Its paper. The only value it has is the value that other people give it. It stopped being backed by gold and silver years ago. Since its not backed by gold and silver its value is subjective.
If we do not bail out the banks and the auto makers then they fail. If banks fail then no one can borrow money and because of all the other things people have said no one can buy houses and cars. Without the auto makers people don't have jobs. Not just the people who make the cars mind you. The people who sell burgers to the people who make the cars, the people who mine steal to make the cars, the people who sell insurance to the people who make the cars. Basically everyone gets hit. How hard is all about how close you are money wise to the auto makers.
The bail out sucks but so does a great depression. I forget who posted it but start growing gardens and raising chickens.
