Those people in your link are idiots for the most part, not that I believe half of what they're dating. If you had to take a guess what do you think most of those people majored in? Engineering? Computer science?
I don't think these people are idiots (Posted again in case anybody cares
http://wearethe99percent.tumblr.com/). Take for instance what is now the first picture on the page (I THINK it adds more daily, I'm not sure if it's daily or different times during the day) It is an 89 year old guy. The card says and I quote "I'm 89 years old. Refinancing my mortgages and new interest rates sent me to Bankruptcy. I've lost it all. Humanity before Greed. I am the 99%" Would you seriously call him an idiot? Would you take Cain's stance and tell him to basically suck it up and it's ALL his own fault. Seriously?
What about the (what looked like 15-16 year old) girl who held up a sign saying their family couldn't afford to pay for her dads cancer treatment and he couldn't afford to stop working, so he died. Or the husband that held up a sign saying his wife worked 80 hours a week to pay for her cancer treatment. There are pages and pages of this stuff. Calling them "idiots for the most part" is dangerous. It's turning a blind eye to those that have serious problems and are getting zero political recognition.
These are not all lazy college grads who partied their asses off in college while majoring in communications who after college thought "well shit, I fucked up, I think I'll protest". Yes some are like that, but that is NOT enough to discredit the entirety of those without jobs who can't make ends meet. I think Cain made that leap in his statement, and I find it faulty and dangerous.
