I think it's plausible if you think of it in periods or "waves".....Capitalism may indeed be superior entirely, or it may only be superior up until a certain point, and then once it reaches a certain level of power (political/regulatory/cognitive capture) it could cause certain levels of progress to stagnate...and if adequate capture and ~censorship of information production & distribution has been accomplished, people may never be able to realize the position the system has assumed (or, some may notice, but their messages may be censored or disbelieved).
