It is totally fiction. Shareholder's meetings only vote on two sorts of issues.
(1) Here is a list of officers. You may vote FOR or AGAINST them. T=It is exactly like the USSR: Joseph Stalin is Chairman. if you are a party member you may vote FOR or AGAINST him. Nearly all corporations fail to provide a list of candidates, as in you get to choose between Hugh Jass and Jack Cass.
(2) Here is a list of proposals. You may vote for, against or abstain. They are written in legalese and are usually not very intelligible.
Management always recommends that you vote FOR everything proposed.
The only exception that I know of is TIAA-CREF, that always has three or four candidates, with their bios and a personal statement of their concerns.
When TIAA-CREF has propolsals, they explain them clearly, with how a PRO and a CON vote might affect the company and the shareholders.
Corporations are NOT "anything but people". They are artificial entities that prefer to be dictatorial in nature and are not respectful of the intellect of their shareholders or their customers most of the time. A corporation many have many shareholders and officers, but the shareholders are normally ignored and only a couple of the officers always speak for the whole shebang.
YOu are never going to convince me otherwise. Hobby Lobby and Alito, Scalia, Roberts and Thomas can shove it, and rotate it until it bleeds.
I know from TIAA-CREF that corporations do not have to suck and treat their shareholders like dummies. They do this because they think we are dummies, apparently.
