Depends on the incentives, doesn't it? Most companies are for-profit, they don't have any incentive to do good beyond what PR requires. If you set a company up as a cooperative, you'd likely see different results. It's pretty common for housing in Germany, I'm a member of one and am living in one of their apartments. I pay below market rate, they take great care of the project, are super responsive to issues and they usually pay 4% dividend to all members.

I don't know of many cooperatives that do "normal" business, but I don't see a reason why e.g. a cellular provider couldn't run on the same model, being perfectly aligned with their customers' interests, because the customers are also the owners. Mondragon Corporation in Spain comes to mind, but I have no idea whether they're friendly to smaller competitors.
