Leaders of departments (i.e. the government equivalent of a CEO) are dragged in front of congress all the time.

The government at least has a theoretical obligation to promote the public good. It isn't much but it's better than corporations whose only obligation is the shareholders.

The government is also subject to safeguards like freedom of infermation requests which level the playingfield somewhat.

I'm not saying that the government is good. I'm just saying that corporations are much worse.
