The point he is making, and that you don't seem to understand is that you need to live within your means. If your means consist of $8 an hour, $320 a week, $1000 a month after taxes, that means buying bulk oatmeal instead of Raisin Bran. That might mean eating beans and rice instead of stealing steak.
Having been a poor, starving college student before, and living off of ramen noodles, mac and cheese, hot dogs, etc, I know this reality. I wasn't smart enough at the time to realize how unhealthy a lot of cheap food is, and if I had to do it over again I'd eat beans and rice and oatmeal as they're much more healthy.
Anyway, the point he's trying to make is that even if you are extremely poor, making $8 an hour, you can choose to live on a budget. Rent a room somewhere for a few hundred dollars a month, buy cheap food for a hundred bucks a month. If you're smart and live within your means, you can be saving 10% of your income even with only $1,000 a month. Work a second job, pick up more income. Maybe splurge and buy some meat once in a while now that you can afford it.
If you're getting a $200 payday loan every week and paying $250 a few days later, you're just plain stupid. That ends up taking $200 a month out of your money. And $200 a month can buy a lot of oatmeal...
The point he is really making is work hard, read your bible, and shut up. Everyone can make it, just do those three things. And if you end up broke and having wasted your life, like so many others, at least you have heaven to look forward to.
But each to their own, and what they want to spend their time on Earth doing.
