I think it's just perceived that way. I know many, many highly motivated productive people who have been essentially given money by their parents. Free ride so to speak.
My kid will have most things paid for by her parents. Schooling of any sort she desires. She basically wants for nothing. Sure she could,go,off the rails but we'll see I suppose. So far straight A's and 11hrs a week of competitive dance lessons with all recitals, comps, and workshops being over and above that.
But I went to school with kids just like her who were handed every opportunity by their parents. The majority of them I'd say aren't lazy. They are extremely successful highly educated people.
