Why is the economy so bad? and what was the cause of the bad economy in the U.S?

You are an exception when most people your age have not got a clue and simply don't care. Apathy. The bottom line is because the US and other countries use a FIAT money system.

This system allows for the creation of "money" out of thin air, backed by nothing and loaned out with interest to be paid back as real money. When large financial institutions default due to bad investments and increased spending on unpopular wars losing 50 cent on the dollar, the amount coming back falters. The government, in this case US, bails out the big banks with taxpayer money that must be borrowed from foreign countries (China) With no investment, no money.

Manufacturing is lost as it is farmed out to lower wage earning countries and the bubble which once was a strong economy fails. To stimulate an economy, war is usually the only option.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
