Thank goodness they're not.

I work for a cooperative in an upper management role. My goal is for us to sustainably produce great products that serve the needs of our community while being a great place to work for our employees. I couldn't possibly care less what our market capitalization is, other than from the perspective of wanting to serve the biggest slice of our community that I can. But if another co-op stepped in and did that instead, I'd be equally happy.
