Most of my ancestors had none of these. Most also lived relatively stress free lives, owned property, didn't work particularly long hours, and most lived into their 90's.
For most of my 'career', I've worked 60-80 hour weeks. Been stressed out as hell. Own no property. My wife and I's 'dream' involves retiring to a stress free place and yes, doesn't really involve technology. Even that is looking like a pipe dream. Recent studies state that retirement may not be possible for millenials, period. Most of my ancestors were able to stop working in their 60's, and still maintain their quality of life (which, as I stated before, lasted into their 90's).
Technological progress is not dependant on inequality. America and Europe were at one point more egalitarian. And society saw its fastest technological progress ever. Heck, most technology today is still built on the exact same foundations that were developed in the 1950s to 1970s.
The problem of inequality isn't necessarily a market-based economy. But rather the current set of laws that enable incumbents to make higher returns on capital than the rest of society. The problem really is - how do we properly allocate resources while also distributing wealth in a way that is most beneficial to all.
It's not a problem of capitalism vs. socialism vs. communism, or technological progress vs. no progress.
