Broke AF people are still buying ridiculously expensive new trucks, I don't think this will be as much of a problem as you are thinking. Also, some EVs can be downright cheap if you qualify for incentives. It was theoretically possible to get a Bolt for like $3000 after government incentives in certain states before Chevy stopped making them.
You can buy a used bolt with maybe 20,000 miles on it for about $18k. If you're in certain counties in California you can get a couple of grand worth of incentives towards that.

Plus, China's middle class has been gobbling up the BYD Qin and Song EVs.
