Wendy,
The “helicopter money” was between 2009 and 2011 primarily and 2020 and 2021 for Covid. The only year that was not really supply side econ based was 2021. That was giving poor people money. Particularly very impoverished bankers who have been rolling in the dough ever since.
The greatest reason for our current inflation has been the tax cuts of 2017. Covid demanded infusions of money to get a dead economy back to life. The tax cuts never increased production in the US. But when Covid hit the tax cuts caused mayhem in the cost of goods and services.
Coming into 2022 as we left supply side economy behind we got a glimpse of America rebuilding her industrial might. After we were done with supply side economics.
Yes the government has relieved some student debt. In effect our generation has far less student debt because the government picked up much more of the bill at the state schools in those days. We forget how society helped us and begrudge others.
