Government is ultimately accountable to the people. Private individuals are not. Talking about the middle class as the concentration of wealth is laughable. It's the super-rich's wealth that is the concentration, because all that power is held by a small group that have interests and priorities different than the vast majority. A large middle class, by definition, is a bulwark against this, because they are a large amount of people with interests more in line with the general populace. They need health care, good roads, various government agencies. The super-rich really, really don't. Also, if you think a $100,000 salary in the US is rich, you're wrong. It's very nice, but it's not "rich".
