The way I was raised, and I passed on the kids I have been involved with (My own and others) was that we needed clothes, food, and shelter, with some contact with other human beings/ entertainment as the basics. Just about everything else was a want. We might get something as a reward, but rarely. (mainly the parent saw how much you wanted something and made an excuse/ or wanted to cheer you up without "Breaking" any rules....)
Clothing was jeans from sears and roebuck with 1 pair of school designer jeans. If we wanted designer jeans we spent allowance and job money on the difference (Hmmmm, 4 pairs of plain jeans and 1 pair of designer, or spend 20$ per upgrade to have another pair of decent but not spendy designer jeans). We got a handset phone with no services and the cheap sears one when that came available.......(If you wanted your own line you paid for that too....)
Food was generally plain with some fancy stuff on holidays, we never went gourmet, and if you didn't like what mom served, you did without......not starving at all, but the occaisional "Expressing Independance Fast" cut some excess calories...... We did not have Tropical fruit aside from bananas, or fruit that travelled much further than the state next door either if I recall.
Shelter was our own room with our own bed, desk and chair. Generally to our taste, but not expensive, anything else was bought out of the allowance...... Computers came on the scene, and our family had one, it was part of the TV/ Entertainment stuff. We did not have TV's or any fancy electronics in our room unless we bought it from our allowance/ job money.
I and my parents didn't say word 1 when we/ the kids wasted our money. We earned it and how we spent it was our problem......we learned by making mistakes with it, end of lesson!
Holidays and gifts were generally "Cool things of use that they would not buy for themselves" like the Terrarium my sister was lusting after for almost a year, but never quite bought because of something else coming up........ There was a disconnect with the relatives though, useless expensive and fad related......fun in its own way but usually repurposed within a month......
Also we had a "Half hour to the road" rule when we went camping, we packed our own stuff, and had to fit it in our own space in half an hour and we would be on the road, no go backs......... I had a bugout pack before I knew what that was called. I had some problems with things like toilet paper as various stages of growing up happened (mom and dad took care of those communal items....)
Whoa wall of text, but maybe I helped.......
Bottom line, parents provided the basics of what we needed, anything upgraded we did ourselves......
