Why are people refusing to accept the days of low interest rates are over?

The near zero rates we saw during the previous decade were an emergency measure put in place after the 2008 GFC. Historically interest rates have been an average of 5-6% with inflation being 3.30% on average.

So why do so many people keep expecting the fed to slash interest rates back to absurdly low levels when things have simply gone back to normal?

More importantly large cap US stocks are not really dependent on cheap debt and used it more as a convenience so people acting like high rates are holding back their stock growth seems foolish.
