Ugh. This is so stupid. It's like when people say, "All the nerds in high school will be rich when they're older, and all the jocks will be working for them!" Or the whole concept of karma.
Just accept it: life isn't fair. Some people have the world at their feet from the moment they're born, and are filled with non-stop joy from minute-one to death. And of course there are others whose experience in life will be entirely negative.
I hate this line of rhetoric. I was told this bullshit my whole life. People just make up their own reality rather than looking at what is actually happening.
