You assert that a wealth disparity is an inherent power disparity that precludes voluntary consent. How is this so?
I contend that political power disparity invariably includes threat of violent coercion, and claims of socialist equality are false. I see political power wielded for personal gain at the expense of others every day. It is a zero-sum game despite the perpetual rhetoric of its adherents. I also see market offers based on mutual benefit every day despite the distortions of politics in the market.
You assert there is an alternative to the coercion/consent choice. Why do you believe this is a false dichotomy?
