Obama was a communitarian. I'm guessing if you put away the pejoratives and the black and white thinking about individualism v. collectivism and actually read what he said, read about communitarianism as a set of ideas, you might find them pretty agreeable.
To me, the subtext of what Obama said was that the spoils of successful businesses should be spread around -- because lots of people played a part in that success.
So, let's start there: would you agree with me that this is the subtext of what he was saying?
If not, how not? If so, then let's dive into this deeper...
When we make a transaction with any other human being (assuming certain things, like it's of free will, etc.), I pretty much take it for granted that both parties are pursuing their own interests. This includes buying/selling goods, performing a job, hiring somebody to perform a job, making an investment, receiving an investment, lending, borrowing, renting, etc. etc. These interactions of the exchange of value can take many forms -- but, for the most part, I think all parties involved seek to gain from doing so.
I say "for the most part" because it is simultaneously true that people do things without any (overt, anyway) expectation of gain. But this is something that is clearly secondary -- and really only made possible by people having gained through self-interested activities enough to have some level of surplus resources to do things where the benefit all flows in one direction.
So, in the context of my business, when transactions occur with our customers, vendors, lenders, insurers, accountants, lawyers, subcontractors, etc., each and every one of them are acting out of their own interest -- not in the interest of my company. And that includes our employees, too. Their employment and compensation are predicated upon doing gainful things for the business. We do use incentive pay -- but make no mistake that the purpose of our doing this (like the purpose of pretty much everything else we do) is to drive profits. We don't do that so employees can make more money -- it's the other way around.
So...if they're interacting with our company out of their own interests, what sense does it make that the success of the business (and thus some claim to its profits) is due in some part to these other actors? None of them are shouldering the risks, after all. Everybody wants a part of the spoils of success. But nobody wants a piece of the losses. And you really can't divorce these two things. Others will go and take better offers when they come around (which they should!). They'll leave you for competitors. It's really not wrong to say that, at some level, an enterprise competes with the people it transacts business with. That's why we haggle over prices, salaries, etc.
A person is in charge of their own success -- whatever their endeavor. Yes, anybody who ever did anything of worth only did so by interacting with other people. Anybody who has ever thought or suggested they could be successful as Robinson Crusoe is an idiot. But I think that's a red herring -- because I don't know of anybody who has ever suggested that.
But the other people weren't acting in the interest of that person's success, they were pursuing their own needs and wants in doing so. And that's what we should expect them to do. A society -- a group at any level -- is just a collection of individuals (primarily, not exclusively) pursuing their own wants and needs and interacting and transacting with others also pursuing their own wants and needs.
