Poverty isn't hard to solve because "society needs it" but because it is a statistically likely outcome. If you live in a world where everyone has $100, and every day, each person randomly gives $1 to a random another person, you end up with a highly unequal society within a year.

I mean it's necessary to have some system to allocate jobs and resources. Someone has to do the shit work, and someone has to do the easy work, and there are jobs that it's probably not worth paying someone properly to do in their current form.

Periodically I like to imagine how much it would cost for someone doing a traditionally low paid job to get paid a wage I would accept and if I'd still consider the service worth it. Crunch some numbers on how much housecleaning would cost if each worker had to get paid $100,000 annually with 10 days PTO and weekends (or two other days weekly) off working 8 hour days, or gardening, or childcare.
