I think a lot of people might want to be their own boss — because it sounds cool. On paper.
They are however not wired to be productive like that, the kind of "flexibility" they can come up with is less work more play.
But people lacking self-discipline doesn't mean they should be forced into submission — it should still be an informed choice: they should be able to try both, probably fail and figure it out for themselves.
Another problem is that they see lots of counterexamples — bosses who got their position not with hard work, but underhanded tricks or knowing the right people, who indeed only collect bonuses, don't bear responsibilities for anything and don't do any real work — this is a bad role model, but it's very easy to follow.
