Russell was born into a wealthy British family. He grew up in the household of a former prime minister and inherited an earldom. He was able to enjoy idleness due to the labor of other British (not to mention the labor of Indians, Pakistanis, and Bangladeshis who enriched the British empire).
Maybe one day we’ll invent replicators and be able to provide everyone—not only in Britain but in India/Bangladesh/Pakistan—with the comfort of Russell’s idle existence. Until then there is much labor to be done!
