I mean most of the people on here would support the child I think, fiat and all.
However, I can't imagine this in my life. To me you can't get an allowance until long after you have established manners so even if the child was unhappy with the amount they would express themselves differently.
That makes perfect sense. By ripping up their own money and living with the consequences, do you think the child would learn a valuable lesson?
yep, they'd learn that I was going to tape the money back together and trade it for crisp bills at a bank!
honestly it's been so long since I was a child it's hard to say what they would learn
