I was going to stay out of this thread, but a few comments are in order.
First off, I would classify the original video more in the realm of satire. Yes, some of the protesters fit the stereotype, but many are in dire straights. And unemployment is much higher than the government reports, as Tom K pointed out.
Yes, many individuals who are now broke and jobless would not be there if they had done things differently... so they must assume part of the blame. But blame also rests on the shoulders of our government and "greedy" businesses.
Regarding greed... most people are not greedy, they just want to live a good life, and this applies to many corporations, as Clint pointed out. Anyone who wants something for nothing or demands that "someone" take care of them is "greedy" IMO. This includes businesses who would not be successful were it not for corporate welfare provided by the government. We can argue this over and over, but as I have stated in the past, we will never fix this as long as the government interferes with the economy and restricts a free market. They created the vehicle for the financial melt-down with the implementation of the secondary mortgage market so they could artificially manipulate the money supply. This is the root cause, and it allowed the incompetent and unethical businesses AND individuals to make money they did not earn.
So we need to fix this and it will not be easy. The solution is to get government out of the economy, which is not going to happen any time soon. Limit government and there is nothing to lobby for, whether it be corporations, unions, or special interest groups.
The OWS movement does not have a focused goal, and some say that is the point... to open discussion, but it is not going to accomplish anything. They need to identify what they feel are the true root causes, and come up with suggested solutions. Otherwise it is just going to end up in a lot of violence and bad press, with nothing accomplished.
Protest movements can make change happen, but it does not happen quickly. Just look at the Civil Rights and War protests of the 60's and 70's -- changed happened over time. For the unemployed that are participating in OWS, the time spent is not going to improve their situation, and many would be better off looking for jobs than occupying a street or park. And there are jobs out there, but you need skills, education and ability to get them. That is the responsibility of the individual.
