According to DeLong you need teh invention infraestructure.. and you can not have afull invention infraestructure in a high-technology system.

teh problem with cyber-punk sci-fi is the rpoblem of who sustains the whole research-apply-mantainence system. You need a good chunk of the population ofr that. That's makes feudalism impossible.

Antoher proof is that the second industrial revolution destroyed the feudalism structure.. and I think the reason is exactly the same. The invention of invention destroys feudalism. DeLong has a full course in his webpage. I think he has there all teh links regarding the transition and how it would have been with a new research structure.

This is not to confuse with high unequality..which you can have (what percentage of the population you ned to sustain th system.. Brazil an ohter countries give a hint..a round 50%..you can certainly have the rest living on begging) but I would say that then the system is highly unstable.
