Taxing Billionaires and attempting to take away their funds does nothing as it always circles back.

This just flies in the face of all the empirical evidence. In fact, redistributive taxation is the primary and only effective means of directing money away from the top.

If you consider the most egalitarian societies today, not only do they have banks and capitalist systems, they also have more egalitarian systems than at any point in human history past hunter-gatherer tribes, and are certainly more egalitarian than agrarian feudal societies that did not have banks at all (which emerged in the late medieval period). At most you could make the case that these systems were slightly more egalitarian some decades ago, but even then the difference is not that significant.
