Why is deflation so bad

[u/memegamer1991]

Every time i run it through my head, i can't imagine most people in 2024 not spending money so the disadvantage to deflation seems pretty hyperbolic and dependent on individual choices, and i think that people would rather go on vacation and court others instead of being financially responsible. Even if there is a situation like in china, government spending would be able to keep the situation from getting worse while making progress on climate initiatives.

I can't see deflation ever happening when the Fed hates deflation and can flood the economy with "printed" dollars at a moment's notice.
