text: One reason its a bad idea is it could cost money for either the kid or the parent. In a recent survey that the Boston Globe did said that parents are less likely to sign up for an activity that cost over 100 dollars. I think this is the most important reason, parents shouldn't have to spend money. Maybe they are in a tough time and don't have a lot of money to spend on sports equipment. Most sports you sign up for you have to buy equipment or there is a sign up fee. If there is a free activity, sure they can do that, but most sports cost money. If the parents want to spend that money, they can. I'm not saying they shouldn't, I'm just saying it could cause problems for less fortunate families.
