They do that because there's two aspects Fiscal Policy, and Monetary Policy.
Unfortunately Congress has continued to make a deficit, and spend this country into excess inflation.
That's why The Fed has to set interest rates higher to offset, and cool down that inflation caused by Congressional Spending.
Without counterfeit central banking, the gobbmint would have to raise taxes or cut spending. Inflation amounts to a silent time theft and tax. It is evil - justified via inane arguments and brainwashing. No coincidence the income tax and Fed were enacted the same year. Central banking, one of the 10 tenets of Marxism, needs to be abolished.
