Yes, there always going to be rich and poor. But we used to live in country where rich owned factory and make 30 times what factory worker make. Now we live in country where rich make money by lying about value of derivative bonds and make 3000 times what factory worker would make if factories hadn't all moved to China.
Capitalism great system. We won Cold War because people behind Iron Curtain look over wall, and see how much more plentiful and delicious cookies are in West, and how we have choice of different bakeries, not just state-owned one. It great system. It got us out of Depression, won WWII, built middle class, built country's infrastructure from highways to Hoover Dam to Oreo factory to electrifying rural South. It system that reward hard work and fair play, and everyone do fair share and everyone benefit. Rich get richer, poor get richer, everyone happy. It great system.
Then after Reagan, Republicans decide to make number one priority destroying that system. Now we have system where richest Americans ones who find ways to game system -- your friends on Wall Street -- and poorest Americans ones who thought working hard would get them American dream, when in fact it get them pink slip when job outsourced to 10-year-old in Mumbai slum. And corporations have more influence over government than people (or monsters).
It not about rich people having more money. It about how they got money. It about how they take opportunity away from rest of us, for sake of having more money. It how they willing to take risks that destroy economy -- knowing full well that what could and would happen -- putting millions out of work, while creating nothing of value, and all the while crowing that they John Galt, creating wealth for everyone.
That what the soul-searching about. When Liberals run country for 30 years following New Deal, American economy double in size, and wages double along with it. That fair. When Conservatives run country for 30 years following Reagan, American economy double again, and wages stay flat. What happen to our share of money? All of it go to richest 1%. That not "there always going to be rich people". That unfair system. That why we upset. That what Occupy Sesame Street about.
(There's also a great Cookie Monster follow up, in which he says "In theory, this country a democracy, where everyone who share resources also have say in how resources used. In practice, ordinary monster have very little say, and super-rich basically do whatever they want and make government do whatever they want.")
