The mechanistic reasoning might be plausible, but is there any actual examples of a modern capitalist society regressing back to some form of feudalism to any significant degree?
The point where I'd be worried is when a single company is the majority of a country's GDP or has complete control over the government. The only examples I can think of that even get close to these possibilities are South Korea's Chaebols or Hong Kong's corporate voting block.
Isn't that like the definition of (clasical) liberalism?
