The document discusses how powerful industry leaders often try to prevent entry of new enterprises and innovations to protect their capital investments. However, this can create a positive-feedback loop by preventing capital from investing in profitable new opportunities, leading to an economic stall. The author cites a struggle between capitalist and capitalist as described by Lange, who suggests that attempts to block economic progress always fail due to the constant search for innovation by entrepreneurs. In the long run, productivity continually pushes costs and prices down, forcing profit margins to shrink. Despite this, some economists like Keynes have expressed optimism about the prospect of nearly free goods and services in the future.
