I have been making money since I’m 12, babystting, working n stuff- and spending on what i wish, and what i need. My parents dont make a lot of money so i really didnt have much choice, but to live on my money; which im actually grateful for. It taught me the value of the dollar, money management, prioratising, budgets…etc.
So I think it would be a great thing for a teen to work hard for their money and spend it how they wish…if they mess up, they learn- cuz its their money, and it means more.
