Suffering is a part of life, such that we measure our lives against our suffering.
Remind the wealthy capitalists who live in opulence of that profound truth when they start complaining about their workers asserting their legitimate rights and interests. You only direct your appeal to austerity at your fellow workers, not at your capitalist master.
Yes, "master". Even Adam Smith, the father of capitalism, identified capitalists as masters of their workers:
"What are the common wages of labor, depends everywhere upon the contract usually made between those two parties, whose interests are by no means the same. The workmen desire to get as much, the masters to give as little as possible. The former are disposed to combine in order to raise, the latter in order to lower the wages of labor.
It is not, however, difficult to foresee which of the two parties must, upon all ordinary occasions, have the advantage in the dispute, and force the other into a compliance with their terms. The masters, being fewer in number, can combine much more easily; and the law, besides, authorizes, or at least does not prohibit their combinations, while it prohibits those of the workmen." (Book I, Chapter VIII)
I realize that you don't care about having a human master, but some people don't accept having a human master, only elected leaders that they trust and are accountable to their subordinates.
