Why not just have a heavily regulated capitalist economy that uses protective tariffs to restrict foreign competition? Then break up monopolies with anti-trust legislation. Lower taxes on the everyday and put taxes on the millionare + classes. Then enact stronger labour unions to protect jobs to create a prosperous middle class? Regulate Natural monopolies into utility companies.
People still can become millionaires and capitalists, but the money will be concentrated in the hands of the middle working classes. Therefore, wealthy heads of General Motors, Dow Corning, AT&T, and the like can still get paid fat stacks for creating successful industry they can reinvest into expansion or their personal wealth while the working classes get to adopt the best sides of social capitalism. Consumerism, plenty, decent wages, and incentives.
