Anecdata: I lease an EV for $200/mo on a 3 year 30k miles/year lease. Definitely can see this work.
Leased cars would logically depreciate much faster too considering people won't look after them as if their own. A car worth 30k would most likely be about 15-20k after end of third year; but company would've made 36x200=$7,200 excluding any upkeep costs!
The only explanation must be what we are sold for 30k must cost something like 5k at the factory for these companies to be viable.
Guessing they are maybe keeping the federal/state incentives for themselves?
There is no way the owner makes any profit from that for 30k+ USD car.
