An established EMS company like Jabil has huge economies of scale and tremendous in-house resources. They have long relationships with suppliers and consultants. A startup can't possibly compete with that.

Perhaps it's worth the effort to have some manufacturing and expertise in the US?
So what you're proposing, yeah pretty much doing that.

Rent (for employees) is also very accessible in the nearby area, nothing close to Manhattan or some swanky neighborhood in BK. (I live nearby)
In my opinion, especially in technology, its just hard to operate at scale and not produce products in China. Not only is their labor force less expensive but the parts that you require are manufactured there as well.

Point being you could find much better locations than Brooklyn without going straight to China (while keeping your own self in Coolsville).
That's a pretty big if. But truth be told, most things don't need to be ultra-high-quality with ultra-tight tolerances.
Where's your iPhone made?
China gets a bad rap for the lowest, barely passable spec crap that gets made and sold by vendors seeking the lowest possible COGS. It's not that China can't make iPhones; it's that they get asked to make cheap shit in a lot of cases. And they can happily do that, too...
The fact is that average productivity of an average American is so high today that it does not make sense anymore for most Americans to do a lot of those jobs.
This makes life difficult for some people at the bottom who have no skill and I think as a society we need to solve that problem. But I see government regulation and unreasonably high taxation as primary barriers to do anything.

Coastals might feign confusion, but that spoke to lots of folks.
