A workers' union is more of what you have described. But for the people in the union, we already have "one person, one vote". Union donations, even though voted upon by the entire collection of members, is less than 10% of corporate donations to politicians. While a corporation's donations are at the whim of the CEO, or at best the small group of like-minded (and salaried) board members. The 20 or 20,000 workers that actually make up the corporation have no say at all in the donations.
The owners of the corporation are the ones ultimately controlling its actions, even if thru electred directors & hired managers.
If the employees want to be in charge, then they should buy stock, otherwise their relationship is that of providing labor for compensation.
Note: I also favor unions & any other group being able to lobby government.
BTW...corporations CAN "marry"(merger), "adopt" (takeover), make "wills" (inheritance), and they most certainly vote with their money (i.e. The CEO/board's discretionary funds).
That is merely metaphorical. Corporations are neither married nor single, don't adopt children, & don't enter voting booths.
But I would suggest 2 things for this conversation.
1. Money is NOT free speech.
I hear that a lot, but without money to buy a venue, speech is greatly curtailed. So money is entangled with speech.
Why else are political parties amassing great war chests? They buy ads to get their message across to the public.
2. Regulated capitalism is good. So stop slamming the bribing corporations.
Just what do you think I'm advocating?
Instead focus on the elected politicians who take those bribes and act on the wishes of the corporations. Ban lobbyists (all groups). Outlaw all profits from speeches, books (based upon their terms in office), etc...made by politicians during and after their terms in power. Cut their salaries to barely survival levels (or to minimum wage plus whatever healthcare the populus has).
Political office is meant to be the sacrifice made by an individual in order to help the common good of the masses. It was never meant to be a career....and certainly not a profitable one.
Let's just say that I'm not in favor of the high level of regulation you are.
I believe it would lead to even greater censorship, corruption & poor representation.
