I happen to agree with Alexei's stance more or less. There's nothing wrong with making money and using it for your personal enjoyment. However, when you're running a multibillion dollar corporation--an entity existing only on paper whose sole purpose is to amass capital, and then use that capital for the benefit of your on-paper-only corporation to the detriment of the people around you, well, at some point, someone has to say "enough is enough".
I mean come on...Koch Industries, any "too big to fail" bank (ahem Glass Steagall), any company wealthy enough to simply buy up patents and then sue rivals (or smaller entities) for "copyright infringement" or "patent infringement" or any number of things that companies with legions of lawyers do to say "hey I don't like the fact that you're competing with me, so rather than compete with you, I'll try to sue you out of business", and so forth.
Capitalism works because of the idea that humans are naturally greedy and will want to produce more to improve their own economic situation, and by doing so, produce a good or service that someone else wants. However, corporations distort that by turning into parasitic multinationals, outsourcing jobs, importing people, and generally cutting as many corners as possible to fulfill their legal fiduciary duty, which is to maximize shareholder value, not to A) Create jobs (hence you know that anything the right wing says is complete and utter BS on this one) B) do some other beneficial thing which comes about only as a side effect of their main raison d'etre, which is to maximize shareholder value.
This is where the role of government comes in--realizing that corporations are out to fuck up as much as they possibly can if it means more money. By creating more laws and rules and regulations, it adjusts the procedure for corporations to maximize shareholder value, ideally, it adjusts them so that the only way they maximize shareholder value is by creating goods, services, and jobs.
