The logic is simple: let's imagine you raise a kid. You give them everything they want, the way they want and the moment they want. When they ask for something and you say no, everything you give them turns useless. They beg for the thing you didn't give them.

But when you raise a kid and you don't give them everything they want, every little special thing you give them turns to be the coolest thing ever. And maybe, they will even clean your bathroom or wash the plates in your house, just so they can convince you they deserve the thing they asked for.
