As human beings, we all tend to compare ourselves to others. It’s a natural part of life; whether you want to do so or not, as you learn about how other people live their lives, you make comparisons to how you are living, and even judgments on how those other people live. It’s hard to stop; as long as you want to know how other people are living, the comparisons will occur.
Especially when it comes to money, and the financial success (or lack thereof) had by other people, the comparisons and even judgments tend to flow readily. With money, you can break the current standing of yourself and any others down into a precise figure, exact to the last cent, and compare where you stand. It doesn’t hurt (or help, if you consider this a bad thing) that you can easy find lists of the top billionaires currently living, if you want to see how far you have to go before you are the richest human on the planet. (Heck, if this planet isn’t enough, you can check out the richest fictional characters, and see where you stand next to likes of Richie Rich, Jed Clampett, and Tony Stark.)
