Is there a better way to kill inflation than raising interest rates? (abc.net.au)

Yes, dramatically increase supply chain and flood the market with goods.

Don't ask me how to do that though.

Mandatory retirement savings that would change as inflation moves up and down. Also, decrease government spending. These days a big chunk of what the governments spends is borrowed. That borrowed money adds to the money supply which ultimately adds to inflation. These ideas have 0 chance so interest rate is the only way to deal with inflation.
