Personally I think they should pull out nevertheless and make an example out of NJ. That should give enough signals for other lawmakers not to come between consenting parties.
If Uber left, it would look more like NJ made an example out of Uber. Other states would see NJ's success in beating down Uber, and might be inspired to tighten their own labor law enforcement.
Also, Uber would be leaving behind a very lucrative market in NJ: it's the 11th most populous state, 3rd highest in income,[1] and a large part of its population is in the NYC metro area (high population density, lots of rides to commuter trains, etc.).
Uber's not some irreplaceable God's Gift to Man.
but hey, it's easier to sleep at night when you just dismiss opposing opinions due to their lack of the exact same life experience as you?
