Nearly every teenager get pocket money, but some of them have to work for it, for example help in the houshold. And I do not think that they should complain about when they have to do a little fork for their pocket money. I think this is a matter of course.
When children and teenagers learn early that they have to do something for their money, their future would be much more easier. Teenagers should understand that adults do not sit on the couch, watching TV and get money for doing nothing. Only when you work, you get money to survive in life.
I also would argue that when teenagers earn their money they will begin to value their money. They would not spend it for unnecessary things which they only buy because it looks sweet or cool, but they do not really need it. I think working is a good motivation to save the money for something they really want, for a example a computer game or a trip to Disneyland.
To sum up it is no big deal to give a hand in the household for money. Sure, if someone has to learn for school the parents would understand that. School is the most important thing, the mainwork for teenagers.
