I completely understand the parent comment and I don't think it's a misunderstanding. The idea is that a rich person doesn't care to think through that situation using all their reasoning capabilities, as they're more focused on the long-term; they spend their time thinking about how to get that promotion to prepare for their children's college funds, or something of that sort. An example: I was raised by a single mother in poverty, where she would try to scrape by and live on welfare without working, year after year after year. She would only think about tomorrow's expenses, and she'd do a great job budgeting to make sure we had enough food to eat and so forth. As a child, I would show her job listings, explain the value of utilizing her assets as well as she could (she had her inheritance invested terribly), and all that. She would never be able to understand it, as she couldn't think that far ahead with all her mental capacity being devoted to making the best decision to save $50, as mentioned in the other comment. In conclusion, optimizing those tiny financial decisions often leads you to neglect the ones further out. That's the issue the parent comment was highlighting. Also, traditional economics isn't a fool if you account for the limited economic reasoning capability, and consider that reasoning capability as a scarce resource to be allocated.
