I have run and worked for businesses in which dissenting views were important to our success. I don't personally find your argument persuasive.
But I do know people who find that kind of thing very persuasive: I think it would most appeal to the type of person who believes that groups of people should be managed in a strict hierarchal manner, with the people on top managing things for their own benefit.
And—confirmation bias alert—IMO that's absolutely what both of America's parties do, and why it is difficult for their voters to get even of a fraction of the benefits that the donors (who may donate to both parties) enjoy.
