Too many people under 35 think interest rates are high right now. They are not.
The average Fed Funds rate since 1955 is 4.25%.
US economy was able to grow very robustly at about +4% per year pre 9/11 with interest rates of 5-6%.
No parameter is fixed in macroeconomics. When one parameter changes eg rates, it often gives unexpected results because all other parameters are floating too.
