You kill cancer by starving it of blood and oxygen supply.
You kill Big Government by starving it of money supply - revenues and borrowing limits.
Ironically, the Federal Reserve may help shrink Government by raising rates and inducing a recession. The Fed's attempt to stomp out inflation could also have the unintended consequence of stomping out Government spending as revenues decline and Debt Interest payments increase.
May not lower tax rates, but it may starve Government of the cheap money that allows it grow unchecked.
