Your belief system isn’t congruent with US labor law. Why leave when you can make your existing job better?
Your other comment indicates they should have to amass 51% of company shares. Ridiculous. Their ability to organize and vote to do so comes from their labor rights, and is precisely why they don’t require capital (per labor law) to have a say.
Businesses can be built without capital. They cannot be built without labor.
