It’s meaningless unless you get rid of the Federal Reserve.
Frankly see my first post in this thread- (Go read “the creature from Jekyll Island”) becuase even if the gov collectd 0% they could still function becuase they would be allowed to “borrow” that money by creating it through selling bonds, and co-operation of the Federal Reserve-they are the poision that is killing America!
For a while, not indefinitely. The currency would eventually plummet with full debt monetization.
