Doing nothing about it is the free market option. And, no, it will not be a disaster, except for those who are unfit or unwilling to adapt. A century ago, farmers were 31% of the labor force. Today, they're less than a percent. But the country as a whole is far richer.
Trying to solve the "problem" via legislation will impoverish the nations that try it. Unless, of course, we "achieve" the libtard dream of world government, in which case the whole world will be impoverished but just won't know it, having no standard of comparison.
You don't get it.
There will be almost no jobs. There will be nothing to adapt to, except collecting your monthly allotment of government ration coupons.
Even now there are not enough jobs to go around because most low end jobs have been replaced by automation, and the level of the jobs being replaced is continuing to rise.
Soon whatever you do, will soon be done by machine.
And all of us will be helpless to better ourselves.
The "geniuses," the nerds, who are bringing this upon us, have their own Nazi like agenda of how the world should be.
As nerds, they looked up people who were more successful then them because those successful people had strong social skills, as something that needs correcting.
So these technology nerds love the idea of creating a world that puts everyone out of business and brings them down to the same level.
Just look at the political mindset of Google, and what that company thinks your fate should be, what your life should be like.
They and their ilk are re-engineering everything in our society and culture according to their ideals.
It's like some kind of cult of technology despotism.
To use your reasoning: a century ago the United States had much smaller government, and today we have massively larger government, but the country as a whole is far richer.
