That’s not true. You can reduce household demands by raising the rates which is what they are trying to do now. But the challenge is now the inflation has outpaced them and Fed has missed the mark by quite a bit. Heck they are now taking about raising rate by 100 basis point. A year ago this was unthinkable when meme stocks were on the fly. But you can’t raise the rates fast and not cause spiral in for example liquidity or repo market.

Point is Fed has done a lot of damage. In a functioning democracy, Fed chair would be summoned by congress and Fed would be held responsible for not keeping its dual mandate - price stability (which inflation is causing wreckage) and unemployment ( from an impending recession). If a Fed agency can’t keep its mandate, it’s time to look at its validity.

But of course our elected leaders won’t. They love nothing but delegating to unelected agencies full of so called experts so they don’t have to make hard choices/decisions and bear the consequences from voters. So they just shield themselves with experts.
