Government Money Creation
According to modern monetary theory, the only limit that the government has when it comes to spending is the availability of real resources, like workers, construction supplies, etc. When government spending is too great with respect to the resources available, inflation can surge if decision-makers are not careful.
Taxes create an ongoing demand for currency and are a tool to take money out of an economy that is getting overheated, says MMT. This goes against the conventional idea that taxes are primarily meant to provide the government with money to spend to build infrastructure, fund social welfare programs, etc.
“[W]hat happens if you were to go to your local
IRS office to pay your taxes with actual cash?” wrote MMT pioneer and American economist Warren Mosler in his book "The 7 Deadly Innocent Frauds of Economic Policy." “First, you would hand over your pile of currency to the person on duty as payment. Next, they’d count it, give you a receipt and, hopefully, a thank you for helping to pay for social security, interest on the national debt, and the Iraq war. Then, after you, the taxpayer, left the room, they’d take that hard-earned cash you just forked over and throw it in a shredder.”3
Modern monetary theory says that a government doesn’t need to sell bonds to borrow money, since that is the money it can create on its own. The government sells bonds to drain excess reserves and hit its overnight interest rate target. Thus the existence of bonds, which Mosler calls “savings accounts at the Fed,” is not a requirement for the government but a policy choice.4
