A really good example of such potentially inefficient transactions is children, who do not understand how much time and effort it costs to acquire money, are in the throes of video game passion and a screen pops up saying, "Win More, Only $3.99! Buy Now!"
If they can do that, those children have much larger issues than a $4 charge - they have stupid and irresponsible parents, who are not only providing inadequate supervision, but are incompetent at teaching their children life skills.
Those in-app purchases require an account password - that's a parental responsibility. Allowing the kids to know the password is no different than sending them to the toy store with a blank check. Not only are the parents not teaching their children to take responsibility for their actions, the parents themselves aren't being responsible.

We warn the reader in advance that the proof presented here depends on a clever but highly unmotivated trick. -- Howard Anton, "Elementary Linear Algebra"
