I think the perception that people are protesting because they aren't rich is a bit off. I was under the impression that the large majority of these people are protesting because the rich pay a lower percentage tax-wise than the common man. In this regard, I completely agree with the protesters. Taxes should be fair, and the system shouldn't be slanted to benefit the absurdly wealthy. I remember when Ronald Reagan said the same things Obama is saying now, and the Republicans cheered him for it; but today Obama is called a Socialist. Sadly, I feel that greed has corrupted our entire political process in the USA, and I'm not sure what we can do to fix it (aside from outright banning money in politics). I support the protests, I'm all for the freedom to demonstrate.
I also think the NYPD need to lay off the protesters. I've seen a lot of abuse coming from them, and most of it was not warranted.
