Or they have it completely upside-down:
Those parents who adopt a more enterprenurial mindset are able to make more money.
Thus they pass on this enterprenurial mindset on their children.
Children of middle class workers are indoctrinated into a 8 hour job.
In the same way one can think that children of enterprenurs are indoctrinated into entreprenurship.
Obviously being a company owner will net you much more money than being a worker.
Most middle class people are feeling guilty just for asking for a raise.
Children of enterpreneurs think completely differently.
