> If someone is poor and has a choice between buying a stereo system and saving the money in a high-interest bank account, I doubt you'd have any problem saying that it's in their self interest to do one of those options and not the other
Curious, what would you say is better to do? I could see either one of those choices as being equally rational and justifiable. I honestly lean a little more towards the stereo. Your answer depends on your outlook in life and your interests and wants/needs in the moment. It's not so simple as objective 'data on the situation'. Furthermore, claiming that you can deduce quickly what is rational and right for someone else is a little condescending.
