Most of these measures have been taken before though...Obama's efforts in 08-09, were extensive as well...and adding millions upon millions to government subsidized health care, pumping billions in to the auto industry, sending checks...all those things caused inflationary pressures, I'm sure. But it was largely held in check, because the supply and demand dynamic, for most industries, stayed manageable.
The reason Biden's welfare efforts nuked inflation was that it had already been blown up by Covid. Any conversation about our current inflation issues, without including the effects of Covid, are pointless. Inflation took off because people were spending on and consuming more...stuff...than we had capacity for.
You're choosing to focus solely on Biden's policies...because you hate Biden and far left liberals. When the actual facts are...artificially low interest rates for way too long, led in to a pandemic that shut down the entire world, which completely F'd with the supply chain for most industries, that was then followed by a hyper inflated demand on products and services from sectors that had just shut everything down, and that weren't prepared for this sudden rush of demand...there was no where for anything to go but to create uncontrollable inflationary pressures...only this time, those fancy numbers that Wall Street always talks about, but rarely effect regular folks...those numbers represented the cost of eggs, milk, cars, gas, houses and rent...
Biden's answer was to throw more money at it, to help more people "afford" all those things. It was a bad move. And exacerbated the problems. But neglecting to acknowledge the very, very huge problems that were exploding and unfolding as he took office... Its disingenuous at best.
