There is no way to determine how much money is kept in a bank at any certain point. It varies day to day and at certain times of the day
Nobody decides how much money the government has to borrow. When the government wants to borrow money it has to issue or create debt with the US Treasury.
There could be thousands of reasons people borrow money. To buy a car, a home, to take a vacation, there are too many reasons why people borrow money to list here. Hopefully you got the jest of this answer. There a numerous reasons for the borrowing of money but common ones are; home loans, purchasing of cars, insurance, purchssing of business companies etc. People borrow money in generall because they either cant afford something or they have no money in cash, so they borrow from the bank, the disadvantage however is that you have to pay it back, and what people don't realise is that the bank adds interest to the overall payment if you pay it over a period of time which is not in the month requested by the bank.
when you borrow to much money
Alot.
1 million dollars
That is a question which you should ask your bank, not us.
As much as you want, if you either have or can borrow the money to do it.
none
This depends on how much money you already have. Also, if you have a low paying job, then you won't be able to borrow as much as someone that has a well paid job.
