When I was a kid my mom would complain about how the world was out to get her. She didn't frame it that way, but that's essentially what she was saying. One time she was complaining about lawyers because she was charged $300/hr or something like that. I asked her, "why don't you become a lawyer?" It made sense to me as a 12 year old and still does.
I don't know your mom, and I don't know what she is or isn't capable of doing. I also don't think it's helpful to believe that the word is out to get you, regardless of personal situation. But that said, you're absolutely delusional if you think that everyone in this country who wants to become a lawyer or a doctor or a better-paid whatever is capable of doing it. There are a million different reasons why most people…
"It isn't their fault, and nearly everyone I've met is doing the best they can with whatever they've got."
While I agree with your general sentiment, most people are not doing the best they can. You know what I do 3 nights a week? I have a study regimen, right now I'm working my way through a probability book. A lot of people that could be doing the same thing are playing WoW or watching Big Brother. I have a 1 year old and a 3 year old, and I still make time to study on top of my job as an engineer, which pretty much means that I don't watch t.v., play video games, etc. Most people don't make that sacrifice.
