The overall idea seems to be that you'll have a lot more free cash flow if you avoid stupid expenses. You'll have a job if you have a skill that can't be outsourced. You don't have to have X million dollars, you need a reasonable income and not to waste it.

So, mostly, reasonable points. Worth taking a minute to think about, since our society pushes us toward wasteful spending (most advertising, many TV shows, other peoples' expectations, and so on).
