Not ashamed, but forklift driving will be automated sooner than teaching (probably way sooner).
I'd prefer them to run the most lucrative business they can operate and accrue capital.
I think at some point we'll all be screwed by automation (including teachers, developers, baristas and doctors) and too poor people won't have a reason to exist.
Better to get rich and independent from society before we can print human-like workers in a factory.
