Over 95% of all comments on HN about business come from people who have never run a non-trivial business. This is beyond obvious to anyone who has.

While I am sure it feels great to have and voice an opinion about everything, at some point, in the interest of not engaging in self-deception, one has to be honest in recognizing lack of knowledge.

Put a different way: If you have never had to fire 100 people or more, it might be a good idea to recognize you likely are not equipped to understand that reality.
