I think it's more that if your life really sucks you are a lot more likely to try to escape from it (even if the odds of it happening are pretty low), if you have a comfortable middle class lifestyle you can debate pros/cons and odds.
If you are on fire and there are a bunch of extinguishers for sale but only one of them works, you are not going to debate the price/odds, you are going to buy as many as you can afford to
