your parents dont want you to make the same mistakes they did. which is why they push you harder, to do more, so you have an easier life. then, when you have a life full of material possessions and wealth, and have kids of your own, they'll grow up in a rich house, with daddy to buy them a car and get them a job, and pay for their schooling. they grow up unappreciative of what they have and search for something else, which leads them into drug abuse, and then they grow up forcing their kids to do good in school for fear they lead a life like theirs.. thus repeating the neverending cycle of stupidity and overindulgence.
