In the real world, money must come from somewhere (There must be a source). It used to be that money was tied to a particular commodity such as gold, or wheat, or solver, or some other hard and tangible thing. In today’s world most (if not all) money is fiat money respected by government in such a way as to discharge a tax obligation. In the United States, the state, local, and federal government will only accept dollars for payment of taxes. That is the fact that makes dollars money.
Government creates money to do that which the people have, through their elected representatives, requested that government do. This money creation is accomplished through the following process:
The elected government borrows money from the FED for some undertaking (government overdraws its accounts at the FED or grants the FED some bonds (iou’s) in respect of the needed funds). Once the created money has been spent into the economy, the government then reclaims the created money through taxation or by issuing treasury notes. In either case this takes the money out of circulation (treasury notes are a special savings mechanism that encourages people to not spend the money, but to save it instead). The reclaimed money is used to retire the loan from the FED or to replenish government accounts drawn down to provide the requested services. The sale of treasury notes moves the debt (original loan from the FED) from the FED to the public. The Fed does not own the national debt; the public does.
The total amount of dollar money in the world is the sum of all the printed money (coins and paper), the bank clearing balances of all accounts, and the amount of treasury notes representing the national debt. All of this money is created by government spending that has not been offset by taxation. Note: Bank loans do not typically create additional money in that the loans are repaid.
Obviously, if government creates too much money without taxing then one of two things will happen:
Either the money will lose its value and people will not accept it as payment for the goods and services they provide (inflation), or the rich will get a lot richer as compared to everyone else as they hoard the money in treasuries. This should be obvious to all people who would take the time to think about it.
