Your "outdated socio-economic system" is someone else's "reality". While we are rapidly eliminating jobs for people on the left side of whatever IQ test you wish to use, we still have to pay people for food and to build stuff. When we automate THOSE jobs, we'll STILL have to pay for the energy production, energy usage, and maintenance of said automation, energy production and energy distribution.
I dig that. The outdated economic system is my reality too, but I can only speak for my society. I'm not saying that people wouldn't have to work. I'm saying we could all work less. Stuff will still need to be manufactured and energy produced. But I also know that i live in a society who's needs (overall) are overfilled. Businesses create new markets now to sell their products. They are not meeting a need, they are creating one. It seems that we could reduce our production, work less, and still meet our needs. It just wouldn't be as profitable. That's when the powerful people come in with their needs of more and more profit.
"Powerful people" aren't the problem. Energy and materials science is. Until energy production and transmission is zero cost, or close enough to it that it becomes an advertising expense, the leisure society isn't going to happen. I also don't believe that "Powerful people" are hiding the near zero cost energy production silver bullet. To speculate that it is so leads down the dark hole of conspiracy. Near zero cost energy not going to be in my lifetime, and probably not in my child's either. If the NIF (or any of its analogs) produce a self-sustaining fusion reaction, that will be tipping point. The materials science problem is nearly taken care of, but said materials (Iconel, among others) are too expensive and (again) energy intensive to produce in large quantities.
There is speculation that if we actually get to the zero cost for energy society, mankind will inadvertently self-exterminate. I can see this being a very real possibility.
Sure, I agree that we will need new and better power sources. Zero point energy sounds intriguing, but that's about it at this point; it's vaporware. I'm all for conspiracy theories (I believe they happen more than most people think) but that one has a lot of heat and not much light. I also think that powerful people exert more control over society than most people believe. But there is not one reason for the world being the way it is.
