And yet you chose to only blame Biden.
I blame "Bidenomics". In as much as "Bidenomics" spends more borrowed money increasing the federal debt on unproven technologies.
Again, it was both supply and demand problems - or it would have been both had stimulus measures not been implemented. It's true that we white collar workers saw little-to-no impact on our purchasing power. However, what happened to the purchasing power of workers in industries shuttered (either by fiat or by vanishing demand) by the pandemic? It disappeared. I work in the entertainment industry; I used to work in concert production and still know a lot of people who do - those guys were out of work for something like two years. A lot of organizations are still struggling to get back on their feet.
Aggregate demand was not a problem. The market corrects imbalances in demand. (See below.)
The pandemic in itself did not cause the bulk of the supply problem. People who were sick missed work; some small reduction in production capacity followed. However, government policy that shut down the economy caused both sick and healthy workers to stop production.
After 14 years of "free" and easy money from the Fed's monetary policy and irresponsible fiscal policy by both administrations, the corrective pain of an economic maelstrom was merely postponed. The pandemic was the straw. And, I don't think it's over yet.
A recession corrects imbalances in the economy. It's painful. Companies that are producing goods for which there is insufficient demand layoff their employees and, if bankrupted, have their assets removed. Both employees and assets are made available to investors/entrepreneurs that produce products that people do want.
Again, I understand the phenomenon. What was the alternative? Not helping people who were out of work? As I understand it, the general wisdom regarding the response to the 2008 crisis is that the government was too stingy and let the recovery drag out longer than it needed to - that things could have recovered more quickly if they'd been more aggressive in stimulating the economy. This time around, the people in charge took that lesson to heart and tried to get money into people's hands quickly in order to stave off a serious recession. In that pursuit, they were largely successful.
The alternative was to stop spending money we don't have. If government raised taxes or reduced spending on other projects to increase transfer payments then the eventual pain of excessive borrowing could have been avoided. But both administrations just kicked the can down the road (to keep their jobs, I suppose.)
I no longer follow as closely as I once did fiscal and monetary policy maneuvers employed in Wahington to postpone the inevitable. The last accounting gimmick not widely know that I recall the Fed used to reduce the inflationary effect of its quantitative easing policy (buying junk bonds) of the multiplier effect on the money supply was to introduce paying interest on the all reserves -- required or excess -- of banks held at the Fed. Rather than take on risky loans in the marketplace, the banks just left the funds on deposit at the Fed enjoying a risk-free reward. The multiplier effect on the money supply was quashed. The Fed doesn't make (just makes accounting entries) any money so who do you think paid the banks the interest?
