re: After Trump is elected and everything doesn't magically cost what it did in 2019

You are also uninformed! Once prices inflate they generally DO NOT go back down.
I lived through the inflation triggered in the late 70s that was eventually brought under control by huge interest rates in the early to mid 80s.
I bought my first house in March of 1985 and paid 9.5% on my mortgage. That then was considered an "excellent" mortgage rate since just a few years earlier they were in the teens! People complain now about 6ish% mortgages, you all haven't seen anything yet since the Fed did not raise rates enough since that would just hurt the party of the slave holders in the upcoming election. So much for the Fed being a non-partisan entity.
Inflation was finally tamed and the only thing that made things "cheaper" was inflation was kept at bay for a long time while wages rose eventually eclipsing the prices that had inflated. Because I can tell you practically nothing deflated in price. You must be a much younger person than I not to know this, that and mis-educated.
It's just not the initial round of inflation, it's the inflation on top of the inflation on top of the inflation.
That lasted until this administration, that is just the facts. Read it and weep puppy dog, I'm sure you'll stick your head in the sand.
