1) Corporations, partnerships and other fictitious/artificial "persons" (entities created by statute or decree) exist at the sufferance of The People, and shall enjoy only those rights and privileges expressly granted to them by The People.

3) No part of this amendment shall enjoin any government office or agency from acting officially on behalf of The People, unless such acts contravene this amendment.
4) Political parties are deemed artificial "persons".

What does this amendment do?
1) It revokes the Citizen's United decision, and declares that corporations are not entitled to the same rights as natural people.
2) It allows corporations to be tightly regulated.
3) Since corporations may only have rights that are explicitly granted to them, we can omit rights that have been abused, such as lying via advertising, or protection from self-incrimination.
4) While not eliminating completely the corrosive effect of money in the political system (that's for another amendment), it sure as Hell waters down the damage.
5) It explicitly denies that Money=Speech,
Perfect? No, but its a start.
