Most of those "old" people have worked and contributed 30-40-50+ years to cover their burden!The person the OP described isn't much different than who I was as a young man. It took some embarrassment, lean times, and a few domestic disputes to learn some hard lessons about what is "valuable".
We can only hope that the individual you have described (and the millions more just like him) learn from what is, to many of us, an obvious mistake. I propose we not be too hard on them as there are many organizations that spend a lot of resources tricking young people into believing things of little value are actually of great worth.
I'd also say, old people are a tremendously more costly "burden" on American society than he is. That young man, misguided though he may be, still works and thus contributes to systems that largely benefit people other than himself (the oldest among us being chief amongst those beneficiaries)
