Big business is moving away from capitalism as frantically as is Obama. Sure, the private sector is doing just fine.
They want to have codified monopolies. The contention that Democrats want to “go after the big corporations” and “the rich” is poppycock - it is all about establishing an oligarchy. Those supporting these high tax policies that are in positions of wealth and authority do so because it will discourage / prohibit others from working toward attaining the same wealth and status to challenge their positions.
