Money is a taboo subject. We are never supposed to talk about it. It is supposedly rude to ask how much people earn, spend or even save.
Well like anything, if we do not understand, we cannot appreciate.
These parents take a really good approach to money. They draw out a months salary in dollar bills and then allocate the money to the various bills that will need paying such as groceries, rent, utilities, car etc etc. This lesson allows their children to understand where the money goes and are therefore mindful when wanting something. A great lesson in budgeting and opportunity cost. Article
