Hierarchical top-down power structures are only useful when you need to make decisions fast. Pretty much all other times, you can have a vote. As such, I don't see why an individual ("CEO") should have the power to fire workers (or why he should even exist outside emergencies and only have powers needed to avert those emergencies).

Generally, on a team, people know who does good work and who works poorly and drags others or the whole team down. Given that, I can see hiring/firing decisions being made at the team level. If a whole team is seen as underperforming/redundant within the organization as a whole, then the team should be given the choice of either making itself leaner or severing cooperation with the rest of the company. This is still hierarchical but bottom up.

Regarding your last sentence and your general attitude, I think I'll sever our communication here.
