Money is better earned than given. Giving kids a free allowance versus making them earn it through chores—dishwashing, clearing the table, taking out the trash, or mowing the lawn—shapes their understanding of rewards.
The former, once grown, would be more likely to believe money is theirs to take; the latter would be more likely to respect others’ property and the effort to earn it.
Stochastically, we could observe similar behaviors in reinforcement learning. After all, our world is not that different from a sandboxed simulation.
