Earlier quoted context omitted.
I guess businesses don't need the government laws enforcing shareholder voting rights and minority shareholder protections then right?
No absolutely the government should enforce legal agreements via the legal system. But that's not what this is suggesting, right? This is suggesting the government should treat unions preferentially, not equitably.
Equity is in the eye of the beholder. I don't see how this law is treating unions preferentially, and am interested in how you distinguish it with the aforementioned minority shareholder protections.
