Some (not kids) do work hard to buy it!
My wife is very reasonable in such things, as long as i pay it from my own money and keep enough to support the kids and get clothes/food in the house.
I grew up with getting nothing, if i wanted something i had to ask and the answer was, "when you're old enough to work, you can work for it, then you can buy it yourself, That is when you're end school and start working, vacationjobs money goes on your account that is locked till ur 18, till then you life with what you get from us if it's needed and usefull for you future"
I'm not gonna say it's a good thing, i know the value of money, but the back side is (not always, but i feel it that way), you tend to buy stuff faster, stuff you know you wouldn't get when you would still live with you're parents.
Anyway, at 38, working, having wife and 3 kids, i can say, if i can afford it, and i really want it, i buy it.
I'm not raising my kids the same way, but the also don't get everything, the gotta learn how to have fun
without stuff to and playing outside is still the best you can get.
