I don't think anyone is protesting hard working entrepreneurs that earn their money and provide jobs for others. I don't think they are protesting the investment managers that earn a fair wage.
I think they are protesting the likes of thieves such as Bernie Madoff and his lower-level wannabees, and then the bailout of the industry that fosters them. I would expect right-thinking people to be out there with them instead of parroting tripe from "Refer Madness", the 60's and the McCarthy era.
There IS a great deal of disparity in the world with business and entertainment personalities, athletes and team owners and many others making more money than anyone could ever spend in multiple lavish lifetimes. "We the People" pay for all of it in the cost of cereal, gasoline, electricity and waste disposal, and shipping for bee keeping materials, just to mention a few.
