Yeah, the guy sounds like a huckster for sure. And much of his logic is flawed: "If expenses rise unexpectedly and surpass your monthly income, then you have no choice but to draw money from cash reserves or investments or go into debt. If your expenses later return to normal, this debt may be temporary, but you’ll still end up paying extra interest or losing interest on your depleted savings/investments, which takes money out of your pocket." The same thing could happen if you earn a variable income: what if you had some large, unexpected expense and also had a bad month for income? Same result, maybe even worse. The only solution is to live consistently below your means and save up a good-sized emergency fund - that advice works whether you make a "fixed income" or not.
