I'm sure that kid will feel the same way about paying for your Social Security someday.
What is your thesis here, I shouldn't be annoyed by children because one day I will be old? Not sure I understand that logic. "Being annoyed" isn't even a proper choice; if I could turn it off, I certainly would. In fact, I would say that the ability to turn if off for a few hours at a time is worth about $50-100 to me......
