The British government is directly responsible for the possibility that this discussion of "taxation without representation" is happening; colonization, trade, etc.
Sometimes when you stand on the shoulders of giants, you realize that the old ways were lousy. America as it is today wouldn't exist without slavery and Native American genocide.
I'm not comparing Capitalism to Genocide, but I am saying the form of argument you used is ridiculous, because I can use the same argument to defend awful things.
If you stop and listen for one minute, people like me are saying, "Maybe the current system is TOO excessive, and should be reigned in, in some ways." We think laws should help fight the excesses of unchecked capitalism.
We're not proposing the "share everything" that Kasparov ridicules, and posing our argument that way is an absurd straw man.
That said, I don't represent a united front of people who believe identically to me, but your argument is so absurd that I think it might practically be targeted at only a tiny minority of people currently saying anything negative about corporations and our current means of economic growth.
