You raise good points, but I was only approaching the issue from the perspective of nigger welfare. It is true that a lot of work has been obliterated by automation and technological progress, and a lot more will be eliminated in the years to come, and that we'll have to find alternative occupations to 9-to-5 employment for people - but it is also true that current welfare benefits shiftless niggers.
Welfare gives them an income on our dime, it enables them to participate in society, it enables them to breed and feed their niglets, and it makes them shittier from generation to generation, if you can imagine such a thing. That's the reason I'm against the welfare state: because, like all programs taking care of the "poor", it a program to help niggers.
But more neutrally speaking:
What you're describing has already happened to a large degree (the "real" labor market participation, meaning the portion of the working-age population doing real work) is probably around 40% right now and it would show if we eliminated HR, trimmed down managements, and eliminated overblown government bureaucracies. Incidentally, doing that would also render most working women unemployed and destroy the Black middle class, which lives on government money.
The standard excuse is that technological progress will create new jobs, but that's obviously not true in the limit. Only so many baristas and fun managers are needed, and not enough to serve as the foundation of an economy. In 10, 20, or 30 years, automation will do to white-collar jobs and the service sector what it has done to blue-collar ones and agriculture. We're already seeing automated servers in fast food restaurants and self-driving cars. It'll only be a matter of time before AI will start do develop software and design buildings. The human body has already been replicated, so to speak, and the human brain will be next. At that point, we'll be faced with three crucial issues:
1. our own obsolescence in providing for our own needs,
2. what to fucking do all day, and
3. who will do the ever-fewer remaining jobs.
These are all weighty questions and I don't have answers for them, but I do know that it's imperative that, if we create a paradise, it will have to be a paradise without niggers. It will have to be a National Socialist paradise, where the genetic and societal poison that is the nigger will be denied entry, lest he bring in his shiftless and criminal ways, now free to rap and fuck bitches all day because automatons do all the work for him.
If all our needs can be fulfilled, that will demand a strength of character all on its own. A strict eugenics program will have to be put in place, so that the fat and indolent - even among our own people - do not proliferate, and turn the whole place into a hedonistic hellhole in which everyone walks around with crotch-attached dicksucking-bots and cheeto-infusers, while Tyrone fathers the next generation of children.
