Do you mean decay or stagnation?
What you described is Socialism
That is exactly what I am describing, and it is exactly where technology will put us within a generation.
It's already happening all around us.
The other day my washing machine broke. I called repair, and they wanted $100 to come and look at it.
My brother says look up the problem on the net, and next thing you know I find out what part is broken, located where to buy the part online, and find a video how to install it.
It won't be long before I won't even have to go through those steps. My washing machine will know what part fails and order it online itself, it will be delivered by drone (truck driver out of job, truck mechanics soon follow, gas stations sell less fuel, fewer stations needed), the part will have a strip on it that communicates to my smartphone the link to online installation video, and repair business goes belly up.
And the accountants and lawyers and suppliers of business products lose a client or customer, they get squeezed. Eventually they're replaced anyway by artificial intelligence, etc.
But I do not believe the process is inevitable.
And though it may be dangerous to bring this process under control by some kind of legislation, not doing anything about it will not just be dangerous, but will be a disaster.
A law to stop progress? Will there be government hitmen to stop the automation?
Will they throw their wooden shoes at the robots?
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.
