Teens have very little financial responsibility. No credit cards, mortgage, kids, loans, etc. Therefore, any money they do have, is considered disposable. The elderly, on the other hand, have less of a disposable income due to many factors- rent, medical expenses, etc. So, even though the elderly may have more gross income, they have less net than a teen would.
I do think that each generation tends to become more and more dependent on the government to help them. That is one of the problems with this country. Rather than take responsibility for their lives, they would rather the government do it. Sure, there are exceptions. But there are so many other influences that foster a society of dependency. And there are many people to blame for this, but it ultimately belongs to the individual.
Back to the healthcare, just found out that my medical coverage- and all that is offered by my employer- now covers brith control! Amazing. :)
