In his case it is also a lie. But then I doubt he writes anything that is not a lie.
You're not one of those people that believe people that make more money are better than those that make less are you? Feel free to believe what you want.
In point of fact I prefer to think of myself as an 18th century serf since if you can't quit work tomorrow you are no better off than a wage slave.
However I make good money, not Brad money but good enough, and more importantly I live well within my means and so while I can't quit work tomorrow, I have everything prepared so that I can quit working in 4 years and be very comfortable for the rest of my life no matter how long I live. If I did have to quit work tomorrow then I still could get by reasonably comfortably, I'd just have to move to an area of the country that has a lower cost of living than Concord, MA.
Living well is the best revenge.
