Your position on this is a little disturbing, and ignores every child/young adult who either grew up poor and had to work, or worked part time because their parents didnt buy them a car or every other thing they wanted as a teen. Or, they just actually wanted a job. I mean, in the US you can go anywhere and there's 15 and 16 year olds working as clerks, restaurant employees, etc. I got my first legally taxed job in Indiana as a 'root beer boy' at a diner when I was 14!
