Yes it's very different. Tesla certainly overworks their employees by basically expecting them to do overtime, and engages in anti-union shadiness, but that pales in comparison to utilising slave labour from a religious minority group they subjugate and have even been known to sterilise, as well as harm family members of those who aren't behaving as the CCP wants them to.

Tesla still has to abide by US environmental regulations, which while not as strict as you'd find in Europe, are a hell of a lot stricter than China.

Tesla still has to follow construction and safety laws that, again while not super strict like in much of Europe, is a hell of a lot stricter than China.

The US also doesn't subsidise exported Teslas in a move to exterminate foreign car companies before ramping up prices.
