Good idea. I'll give up my job as a programmer/doctor/lawyer/professor to an AI, and instead I'll dig ditches, I guess. AI can't do that (yet).
Oh your actual concern is showing - Doing manual labour.
Manual labor in the US pays far less than any of the above mentioned jobs. That's the alarming part--if we're to transition to manual labor and the wages for these jobs stay the same, then workers will be forced to work harder jobs for less money. I'm not sure why you'd expect this proposition to be popular?
Will those jobs pay them the same amount, allow them to have similar qualities of life?
