some people who are extravagant spenders however do have almost an unlimited amount of money maybe from their family’s income so no matter how much they spend they usually do not learn how wasteful they are because they do not run out of money
Well that’s true, but not until they eventually start making money by themselves, and if they’re already used to spending their money extravagantly from their parents income, it suddenly becomes a problem for them and they eventually realize how much of a mistake they’ve been making and then, it becomes difficult to adjust.
Most of the times, even rich parents, regardless of how wealthy they are, often tend to monitor their children’s spending habits so as to ensure that they’re actually spending on things that really matters and not on irrelevances.
