I concur with this. Our kid can earn robux doing chores, and she only earns them once in a while. It often leads her to a period of deliberation, where at first she's like 'I so much need this, I must do whatever chores it will take!'. Then gradually as the minutes go by, she gets doubts, and at some point flips into "No. Way. THAT is NOT worth THAT MUCH WORK!" Whenever this happens, I get sort of proud or satisfied. A lot of times it doesn't happen, she does the chore and gets the reward. But other times, especially for costly idiosyncratic choices, she comes to her senses.

The insane spending sprees/binges shrink a lot, when they are expressed in "how much vacuuming and floor washing am I willing to endure?"
