I have a difficult time understanding it myself. Honestly, I think that those that have these types of problems have issues, first and foremost, with themselves. They aren't satisfied about their life and it's easier to look outward and point the finger than it is to work hard to fix whatever troubles them about themselves...Some examples to demonstrate what I mean

1. The unemployed guy who never bothered to graduate high school or to get any job skills at all who complains about "Them damn Mexicans are taking all our jobs."; or

2. The person who didn't get into law school because their grades weren't even close to high enough who blames "affirmative action" for their failed ambitions.

I could go on, but I've made my point. Thank you for reading and your well-thought out comment.
