"The US is founded on Lockeian principles, not Rousseau's ideas.  You make a huge leap in logic without showing how the American people will get there."

Lol... I don't even know where to begin with this. What did you just learn those names in history class? Society by it's very nature requires individuals to work together towards a common goal. In our case it's the progression of the species. We don't need this to be told to us, and we don't need it to be "Okay'd" by those who wrote the Constitution because it's self evident. Government is merely the way we protect, organize and further our SOCIETIES interest. If you feel that the government doesn't represent you, you have two main options available; stay and try to change things, or leave. Everyone, rich or poor has an invested interest, and therefore a responsibility in keeping our society and by extension, our economy, safe and functioning. That means the government by it's very nature has a responsibility to raise or lower tax rates (among it's other powers) to stabilize itself and our economy.

"Simply saying rich people have a social responsibility is not enough.  Sure people would like rich folks to pay more, but ask them individually and they don't feel they should pay more."

Well that's nice but I don't really care what they think. If you live in this country, work in this country, make money in this country, you have a responsibility to protect the society that allowed you to earn that money.  You may not agree but what you think doesn't really matter. Because when it comes down to the whole "Collective vs Individual" argument, the individual doesn't have a leg to stand on. It's the COLLECTIVE that built this society. It was the COLLECTIVE that agreed in 1776 to declare independence from the British. It's the COLLECTIVE that protects your rights and without the collective you're all alone in the woods. Do you think nature cares about your rights? Do you think nature is going to pay your salary?

Now we can argue all day and night about the ethics behind it all, or about when the collective is right or wrong but that's a whole different discussion entirely. 

 "You are like the crazy man standing on a wooden crate on the street railing against rich people having money. Everybody will just walk right on by."

As I said previously, I have nothing against "rich people". If you have an idea, and you make a lot of money off that idea, that's awesome! I'm really happy for you. But that doesn't mean you're entitled to anything. You never were and never will be. It's the collective that decides whether or not they want to buy your product or service, and at some point you had to use the collective capital of our society to turn your idea into a reality. It could be as simple as driving on the publicly funded roads to meet an investor or taking out a Government funded grant so you can afford to go to college. Or as complicated as using the collective knowledge of our species to build something or solve a problem.
