Besides, companies need to recruit the best talent they can. Genius comes in many political wrappings, as any baseball team can tell you. Google has threatened to pull out of China, I suspect, more because it wants to continue to attract and inspire brilliant employees than because of any other long term calculation. If corporations were persons, then open networks and "slash and burn media" have forced on them what Harvard's Lynn Sharp Paine calls (too glibly, perhaps) "moral personality." This means, usually, moral cowardice.
NO, THE REAL problem is American CEOs using shareholder money to buy their way into public conversations: auto execs on global warming, bankers on macroeconomic imperatives, software companies on education. Meanwhile, who is watching their businesses? Again, a corporation is not a social good; it is a creature of rules, legal and strategic. We presuppose corporate megalomania because we assume that competition brings a social benefit: technological refinements, economic growth, management innovations of all kinds. And in case you haven't noticed, competition is really serious these days. (As I wrote here a few weeks ago, Fortune 500 companies are three times more likely to be selected out--fail of be acquired--than 20 years ago.)
