Did medieval feudalism work?
Depends on who you’re talking to. When feudalism ended, the poor had many more opportunities to class jump out of the lower classes and managed to create a middle class. Also, feudalism stifled creativity more so than most forms of government. So feudalism didn’t work for the majority of people. However, if you were rich, you could do anything you wanted. Education was strictly reserved for the rich, which helped enable them to dominate the lower classes for centuries to come. Not to mention the fortunes that were made (most of them still exist in familial bloodlines to this day). So the upper class had little reason to believe that feudalism did not work.
