Personally, I think it's laziness - too lazy to plan it out better, to learn what you are dealing with, to find outcomes that benefit someone other than yourself.
But there is something to be said for disruption, and understanding it won't be perfect immediately but can be improved beyond the current situation.
It's sort of like overthrowing a dictatorship and replacing it with democracy - the first few years are tough, but the future goes far beyond any dictatorship (it's called, in some places, a J curve).
But that doesn't excuse the laziness in any way, or that often these people do it for only their own benefit.
