Easy. Name one profession within the North American context that makes less money (inflation adjusted) now than say a farmer, loom weaver or laborer of yore.
A grub hub delivery man is wealthier today than a farmer 100 years ago and that's purely because of two reasons: Technology and Unions :)
This argument only works if you have a career (and lifespan) that spans 100+ years. I'd venture a guess that 0% of Grubhub delivery drivers were farmers a hundred years ago.
