There are two important differences: 1) Head of Executive branch is limited by law (constitution, etc). CEO is not limited 2) The Raison d'être of government, at least de iure, is to do good for its citizens, while the raison d'être of corporation is to make money. That makes them very different - not a lot of people would object to removal of nonproductive employees or customers, but many would (I hope!) object removal (through whatever means) of "nonproductive" citizens.
