For example, we have the so-called “six pocket problem.” This refers to a phenomenon in which a child is indulged with money given by the parents and grandparents of both the father and mother.
Another is the “invisible money problem”; that is, a situation in which a child does not feel that they actually paid a price for something, given the increasing use of electronic money. In both cases, children have fewer opportunities to realize, through the first-hand experience of using physical money, that there are limits to the money we can spend.
