Unfortunately there's a fair bit if industry built around charging people who are stretched financially more, but it's possible to avoid that.
Also, that $4K cash for clunkers was a lot. I agree with the author, that would've totally gone into my pocket if they did it today. I still have my old car from college that's worth about $500 now, purchased for $1500, and I don't need it.
Obviously insurance companies make money on average for every policy. If they didn’t, they would go bankrupt. So on average, every time you buy insurance, you lose.
So insure only what’s required by law, or things that would throw your life off track if they vanished.
