The headline/summary would be, in no particular order:
COVID Vaccine Rollout - varied by state and to be fair you have to give the Trump admin credit for development and plans being laid out; but available to anyone who wanted one, on demand, for free, by mid-2021.
ARPA - $1.9 trillion COVID stimulus/domestic investment (local governments, housing, transportation, education, etc) package. Probably juiced inflation to a degree but we would be in a much worse longer term economic situation.
CHIPS Act - $280 billion investment in onshoring semiconductor R&D and manufacturing. Huge returns so far in producing business investments that will translate to quality jobs, strengthen supply chains, and materially improve national security.
Infrastructure Bill - $550 billion of investment over a decade, largest infrastructure investment in generations.
IRA - $900 billion; at the end of the day the name is pandering and this is primarily an energy/climate law. It has spurred unprecedented investment in the energy transition. This could end up being by far the most impactful product of this administration but also the hardest to evaluate in the moment. Impact on inflation is likely negligible but it is projected to reduce the deficit, potentially by a significant amount.
PACT Act - $800 billion investment in healthcare and services for veterans exposed to toxic materials. This was the bill the Senate GOP had to be shamed to pass, think the Jon Stewart campaign around burn pits and all that.
Ukraine - Uniting NATO, adding Finland and now Sweden; and weakening and embarrassing Russia with zero involvement from American personnel.
And most recently came to the table on a border compromise, which frankly I as a progressive think is a bad deal, but exposed the Republicans for the sick, cynical fucks they are.
