We won’t necessarily come back to capitalism, prior to capitalism there was feudalism, which failed due to peasants (the vast majority) being forced to labor too much to live, pay high taxes to their lords, and give most of their crop, eventually falling basically everywhere, most notably during the French Revolution, helped significantly by enlightenment ideas. These same issues can be seen with capitalism right now, we just don’t have a realistic concept of a system or the philosophical revolution necessary prior to the actual fighting to change the system
