Interesting, I've never considered the value/valuation/profits to be a part of what makes a corporation large or not, but mainly focused on just the size of the organization. So a corporation could go from small -> medium -> large without even changing the headcount?
It's about the amount of power and influence you can wield. In a discussion like this, "large corporation" is just a shorthand. When it comes to the legal system everyone should be on equally footing. That they aren't is why these things are so upsetting.
