Yes, life can be hard. And it’s unfair.

It wasn’t easy or fair in preindustrial times. People worked a few hours less on average, but they received less wealth in exchange and had no opportunity to educate themselves and grow wealth. Serfs were not given a choice of job or even the ability to leave or marry without their lord’s permission. Peasants were stuck for life, unlike someone who works low paid 2-3 jobs today.
