No. I don't. I mean that they had the most important safety net of all: Family with the will and ability to help financially.
I'm genuinely curious what financial life lessons you think a middle class kid is learning that a poor kid doesn't understand at a much deeper level.
My own experience is that (some) middle class kids succeed despite their own failures (dropping college classes before the grade becomes part of record stands out in my mind), and then attribute their success to their superior work ethic and intellect.
If most poor people fail to move up the class ladder, then in their same situation you're just as likely to fail. It's either that, or believe yourself somehow innately superior. I can't really think of a third option. It's like the adage about being surrounded by assholes.
You're right. Life isn't fair. But that doesn't mean the person cleaning my house isn't entitled to financial stability. I'm not religious, but I can't think of a secular version of "but for the grace of God".
Life isn't fair but those skills can be individually learned.
