Is it that no human on the planet does any labor any more which could be called unskilled, that nobody cooks or launders or drives? Obviously not.

I don't know, I'm not sure I would call those "unskilled", exactly. Indeed, these days most people achieve those for themselves, so the level of skill required to offer it as a premium, as it were, has only increased.

I suspect there may be better examples out there, though.
