The feudal system of obligations to people who let you use their land predates the modern Capitalism where you hold obligations to people who let you use their capital.

The codependency of industry leading to far greater productive output, but requiring far greater up-front investments, providing the already wealthy a headstart in the race for getting even more wealthy is one of the contributing factors to modern Capitalism, but feudalism predates it by at least a millennium, depending on what point you take as the “birth” of feudalism.

Neither is particularly saintly. Both are systems of exploitation by the wealthy, just the form of wealth has (notionally) changed. Same shit, different coat of paint.
