This scratches the inside of my head

Why can a bank receive billions of dollars without collateral when a citizen has to provide collateral?

Using the same reference to funds:
The US Treasury loaned about $1,000,000 in a week in August 07.
The US Treasury loaned about $400,000,000,000 in a week in October 08

Is there really a separation between borrowing and face value?
Is there a reason I am paying only if I collateralize, and the bank can get money on a few words?

Is it true that the Chinese, Mexican, Russian, Philipine, Japanese, South Korean or you name a government do not have to collateralize?

NUTS.

Just get out of the cab, you are entitled to something for free. No fare, no worry.
