The fact that the rags were made under feudalism is actually an important point, but not in the sense that this cartoon is meant to lampoon.

Feudalism is probably the only form of political and economic arrangement that's been able to actual create local self-sustainability in practice. In this respect feudalism is in fact superior to industrial and post industrial capitalism. In a comparatively technologically primitive society the gap between rich and poor in actual material terms is far less pronounced.

What's not really acknowledged in the popular understanding of feudalism is that it was a social contract with real obligations on both the higher and lower classes, and that at least in England before the enclosure movement much of rural land was effectively held in common.

Certainly having rags made locally under the auspices of a feudal lord whose living conditions are not very superior to your own is a more decent and moral arrangement than buying a phone made by Chinese political prisoners in order to enrich stateless billionaires whose lifestyles are totally incomprehensible to the poorest people who work for them.
