@Darwyn - we've been over this FED thing before. I will deal with it briefly, but that is not the root cause of this. What the FED is doing by charging interest is taxing money. Taxes are bad for the economy, and all taxes are eventually passed on to the consumer - this we all know. It is not, however, decreasing the money supply. All interest paid to the FED is put back into circulation by the federal government on top of the money that the Fed initially put into circulation. So while yes, tax is bad, the FED is not draining our economy, and actually provides some stability. Look at how much the eurozone is floundering without a centralized bank.
Back to the problem with the protests. I think that while the protestors in the Middle East and those in Europe and the Americas share similar traits, their primary goals are different, though the root cause is the same. They are protesting because they don't have jobs, its as simple as that. If everyone had a well-paying job not enough people would give a shit about corporate power to fuel these protests.
But differences in these protests lie who the protestors blame for not having a job. In Europe, it is mostly the government these are aimed at, the mismanagement of which has been deemed a greater failure than the corruption of corporations. The Middle East was similar with respect to the fact that it was directed at the government, but these economic protests quickly developed into protests for more freedoms and rights, but I still think the fuel that started the fire is to blame.
While there is significant animosity towards the government in the USA, I think most of the blame falls on the corporations, whom the people view as not fairly paying their employees and/or not hiring more employees.
So, in a sense the root cause is the similarity of the protest movements, but the way they evolved has been different on each continent
