First of let me tell you that to my knowledge that's WB quote.

Regarding the school system it's not complete waste of time but I agree that people working at board of education have designed it so that we can just become obedient employees in the future.
But important fact is that not everyone can be entrepreneur or business owner therefore it's the parents job to show the path to their kids and help them move towards being a leader not a follower.
If everyone owns a business there will be noone to work for you.

Basically your child needs to be convinced that he/she is chosen one like Wb and supported all the way on this path.
