I don't see what minimum wage has to do with this when as you said, major low skill employers are paying almost double minimum wage.

better wages will

Well yeah all spending would go up if you paid people more. But the US is very good compared to other countries in pay, including countries with similar living expenses.

Imo, the issue with EVs is price, but new ICE cars aren't cheap either. But a ton(most?) people don't buy new cars. My parent's cars(ICE) are from 2005 and 2007, without having done major maintenance. Not only is there a lack of cheap used EVs on the market because they're still new, but also people are reasonably worried about the longevity of the batteries- so would be hesitant to buy one.
