Jobs are not good in themselves, they need to serve a purpose. The reality is that the coffee you brew at home is just as good as the coffee you buy at ten 20 times the price. These are jobs that should not exist
They should exist, and will continue to exist because it's not just about the coffee. There's a social experience of going to a coffee shop, meeting friends, chatting with the barista. That's worth the 20x price to me, and many others.
