Me, 70's and early 80's, no automatic 'allowance'. I did however have that walking-around-money people have mentioned, but I earned it. From about age 10, I was expected to be up and on a tractor at dawn when field work needed doing, and have a couple hours' work done by time school started, and then show up directly from school and do whatever around the shop and barnyard until the regular hands' quitting time and take over one of the tractors and go another hour or two. It wasn't slave labor. Dad said I was doing a man's work, doing that every day as needed, and so he'd pay me a man's wages.... IIRC he paid his hands in the 70's about $75 a week plus house and utilities, so I got 60 dollars a week (they didn't feed the hands, but did feed me LOL.) 50 of it went directly into the savings account, I got a ten dollar bill to do with what I wanted.
When I turned 16 and started driving, I got a 'raise'. Dad gave me the use of an old, worn-out farm pickup--a '62 F100 that was so worn out that it couldn't catch a cold. But it was FREEDOM! Never got to roam much, that work still needed doing, but after layby until harvest, and again after harvest and fall prep, there was some 'free time' that I got to go play. To this day, October is my favorite month of the year, with work done and the prospect of hunting season next on the calendar!
I did get a bit uppity in (I think) my senior year of high school and blew off work a couple times. Come Friday I discovered that the 50/wk going into the bank was ironclad and the walking around money was after that was done. The first week I got nothing, I asked him and he said that I'd only worked enough to earn 37 bucks that week, so he put that in the bank and the next week was all going into the bank, then if I did as we'd agreed years ago, I'd get 7 bucks the third week, since I'd be finished putting that 37 dollar week's 50 in the bank. Had a profound effect on me, especially because it gave me insight into how come he was so tightfisted even after a good year.
Now, my kids, born mid 80's through 1990, got what they needed, and when we'd go into town, if it was in the cards (and wallet LOL) they'd get handed a few bucks to spend as they wished. I'm talking like 5 bucks each. It's interesting what they did with it. One would act all (GTR)-rich and stuff on candy and chocolate bars, one bought hair ties and stuff like that, but one would buy a piece of bubble gum for two cents and call it good. And usually HE would buy that with a couple of pennies he found in the parking lot! I went into his room for some reason, when he was in high school (early 2000's) and found his stash.....it was anchored by a STACK of five dollar bills! Kid had a couple thousand dollars in there! To this day he squirrels away most of his money.
Different kids, raised much the same way, will respond differently to what they get. Proud of how they all turned out, though. All in mid- to late-30's now and independent of *needing* help from the parents. Might not be my choices they've made to get there, but get there they did, and the sausage they made looks good, even if some of the process was messy.
