Governments (remember Hitler) have been known to do more damage than corporations.

I certainly agree with Jon as how a detached-from-human-purposes structure can cause problems.
Still I think we are missing the point when we treat corporatism as evil or as a fundamental problem. Organizational behavior is different than individual behavior so when we treat corporations or other organizations as we would individuals we run into trouble.

Large organizations (corporate or other) must be held accountable for their actions. This applies to humatarian organizations also. Although corporations often support the effort it is countries that go at war.
