That's not how you do it. The US industrial economy is larger than it was in the 70s. Our productivity and output are far greater. But it's all automated. Those jobs for dummies aren't coming back.
We're quickly approaching the point where the average person won't be worth employing. They just won't be worth anything that a machine or a computer can't do better.
That should be the Great Liberation of humanity, but because the rich built an economy based on coercion to labor using starvation as a cudgel, but then covered it up by creating an ideology praising work and drudgery as loyal and honest, now we have a class who thinks if they don't labor they don't have value.
The next great intellectual/cultural revolution will end the normative celebration of forced work. It will recast work as the slavery it is. Most of us won't be able to make that jump but we won't have to since we'll be long dead. The medieval mind couldn't have imagined industrial life, either.
We live in the twilight of a played out worldview.
