The economy is so good right now, people have more spending power than the economy has production power. People (all employed, because we have record low unemployment, mind you) then take this to mean the economy is terrible. People get pissed that their favorite restaurant is understaffed and they literally say "Man this economy is so bad, my Buffalo Wild Wings can't even get employees!" They are literally too stupid to know what they are actually saying is "The economy and job market are so could, people don't have to take shitty minimum wage jobs at restaurants, so they've moved on to better, higher paying, jobs with better benefits." My company can't hire engineers right now, that isn't because the economy sucks, it's because any engineer with a pulse is getting multiple offers.
The only thing the GOP is good at with the economy is spewing bullshit talking points, and giving rich people massive tax breaks and then crashing the job market.
Basically I've learned that people think anything that negatively affects them at all, even if overall the are net better, means the "economy sucks." I really want to know the last time people actually thought the economy was good, 1999? I've been hearing the "economy sucks" every election since 2000 and I was too young to remember it from before then.
