I know pretty much squat about the USA doing this. I try to stay top of all issues but this one has been a bore blah blah. Well The USA did it a second time (QE) and its this week and it really peeved China and Russia off.  
 
Normally I like that. In this case from a quick look,the 600 billion used is money that has no real base. Nothing in the "Fort Knox" to support it. It is funny money.  
 
Yes it real money printed out to buy US Bonds for a reason but it scares me.  
 
I just do not know. I remember in my History books seeing wheel barrels of cash in Germany being used to buy bread.  
 
A flip of a switch and boom The US prints 600 billion in cash.  
 
Can someone drill this QE down and tell me why it helps and does not hurt the economy in the long run??  
 
Is the USA right doing this or it the start of the circling of the Drain for the US.
