All I know is I could afford groceries under the previous president.
Bluntly- this willfully ignorant view is, in large part, why misinformation and bad actors are able to retain a stronghold in social and political issues, since economics are inherently social and political in this country.
If all you are willing to think about and understand is a basic observation that 'things were cheaper', then you are doing yourself and all those around you a huge disservice.
It takes effort to look into the 'why' of things. And it takes effort to understand the often complex answers that comes from looking into the 'why'.
If looking further and understanding deeper isn't done, then all we get is 'well X was better before', and people think there is then some correlation when actual details may show otherwise.
At the same time, yeah, sometimes things were better/worse under a different president and it can be tied directly to policy or action.
In this case though, the fact that things cost more now than 3 years ago is an incredibly complex issue.
It involves economies from other countries, labor markets and wage adjustments, Fed policies, and decisions made by that other president you mentioned.
To boil all that down to 'things were better before' is unfortunate because it doesn't accurately identify root causes.
My goodness, the previous president fought like mad to continue to surpress interet rates well past when they should have increased, and that's long before the pandemic started. He didn't want the good times of free money to end because he knew what would happen to his support if rates did increase. We are, in part, feeling the hit now that we should have felt back in the teens.
And how about all the Trump Checks that went out to everyone, regardless of if they even needed it? That money has to be accounted for somehow, and that plus the subsequent checks are being accounted for now.
It was well discussed back in the teens before covid that the US can't keep operating with low inflation and near 0 interest. It was known before all this happened that things would flip because they had to flip. You can't just go on forever with the good times and not have adjustments/corrections.
Well here we are- in a long predicted adjustment/correction.
