The goal is to keep inflation at a low enough rate that wages keep up.

But they haven't have they? Median earnings are flat with Q4-2019 levels. Averages are higher because those of us fortunate enough to work in tech or healthcare are experiencing boom times, but for huge swaths of the country, things are looking very bleak. Take-home pay is the same, but the price of groceries and rent has continued to climb without abatement.
Obviously wages being flat isn't good when there is inflation, either - if they don't keep up you end up needing more debt because you can't afford to pay for everything out of your regular wages.
We're barely scratching the surface here, but modern economies have a lot of different cogs that really only turn properly in an inflationary environment. It just needs to be a lot less inflationary than it has been.
Deflation is bad, actually. (Inflation slower than wage growth would be nice, though.)
The answer is readily available. https://en.wikipedia.org/wiki/Deflation
Computers have been deflationary since their inception (you can get a better computer for the same money if you wait a year) but people will always value the present more then the future, that's why we've been buying computers regardless. The same principle could apply in theory to other asset classes, you want a house now even though you could get a better one in the future because you value comfort today rather then tomorrow. Spending isn't driven by inflation, it's driven by knowing we have limited time to live.
