I could see the government having a tax program or incentives to build charging stations. But the cars should have needed that, they should be selling themselves.

People who want EVs to save money aren't interested in buying brand new, expensive luxury EVs but that's where the supply was.
Americans don't like having less money in their pocket - who does? - but it's pretty clear that for American car buyers, fuel efficiency is just one concern among many.
After all, a gallon of gas costs the same no matter how rich or poor you are. If government policy keeps fuel affordable for families in the 25th percentile ($41k annual household income) then a family in the 75th percentile ($153k household income) can easily afford the fuel needed to commute to their office job in a crew cab F150, if they so wish.
Of course, that 25th-percentile family's demand for fuel will be inelastic in the short term if their house is a 45 minute drive from their workplace. So when prices rise they'll really feel the crunch - and they'll make plenty of noise about it. But they ain't the ones buying brand new vehicles.
