Free is never free, and as long as someone else is paying the bill people have a tendency to overuse and abuse the program. Image if you will even more people getting someone else to pay their bills. Think about it the next time someone wants you to pay for someone else's EXPENSES.

That is going to happen with any system you put into place. The key is not to let the extravagandized stories of the few fool you into thinking it is the action of the many.
