Under capitalism this inevitably leads to minors being required to do part-time labor.
Minors with walking around money incentivize vendors to raise prices and landlords raise rents, and meanwhile wages fall because the supply of labor goes up. So instead of families needing 2 incomes to survive, now they need 3 (or 4 or 5 or-). Then the economy comes to rely on the additional part-time labor, no one cleans the park unless the teens do it.
