I don't like the idea of waste. I chose NOT to buy my kids super expensive jeans, handbags, and athletic shoes when they were in school. I didn't buy them cell phones or laptops. I did buy them reasonable clothing, shoes, purses while they were in school, actually I gave them a set amount of money to spend at the beginning of school year and in March for purchases for clothes, shoes, and school supplies, over and above list required. We had two desktop computers in family room, one PC and one Mac.
My resources were limited and they knew it. They also knew that college costs would be on them and/or their dad, but they'd have to take him to court to get him to contribute and none of them wanted to do so. Even so, they all managed to procure what they felt was necessary. My daughter spent less on some items, to get one Coach purse at an outlet. The youngest spent $230 on running shoes, but he did win All State. The middle son was always low maintenance and banked some of his allotment.
That is a simplification of each of them over 4 years. While they all had part-time jobs in high school, the daughter and youngest were so involved in extra-curricular their time was limited to off-season weekends. While the 3 differed in interests, abilities, concerns of popularity, they made their choices. All 3 bought cell phones while in high school, I thought it a stupid choice. One bought a lap top, I didn't see the logic, when for no cost could use what we had.
We had tv/cable in family room, living room, my room, and when my parents were with us-their room. When cable was installed, I put outlets in the 3 BR, basement, family room, living room, and kitchen. I would not put tv's in kids rooms. One child bought a tv.
No Tekky, I do NOT have cable now, haven't for over 3 years, I was addressing when I was working a 'real job.'
