It also seems that the concept of a lifetime marrage is starting to break down, and more people seem to want something closer to a friendship - something that doesn't tie the people together for life.
I'm not even sure there's ever truthfully
been a concept of lifetime marriage, honestly, at least in regards to emotional relationship fidelity (fiscal relationship fidelity is an entirely different discussion). It's certainly been a cultural norm given lip service over the centuries, but extramarital affairs have been incredibly common for at least as long and often either tacitly or explicitly accepted. Concept of a lifetime marriage has a lot of self-deception and a lot of economics involved with it, but... relatively little reality, imo.
I could definitely see how more idle time (read: potential for self-reflection and study) would lead to an upswing in honesty regarding the subject, though.
The current problem with work is a distribution problem, more than a cultural problem. The problem is deciding who has to work/study, and who doesn't.
That... is definitely a cultural problem. The distribution problem is trivial -- we've got more individuals than we actually need to get pretty much everything done. Almost every roadblock and inefficiency in doing so is explicitly due to cultural norms. The logistics aspect of it is frankly a non-issue, imo. If our collective societies actually wanted, in their entireties, our various problems solved,
they would be. We could do things by ruddy random lots and get pretty much everything done, if it came to it (assuming a means of enforcement or a willingness to comply, anyway), nevermind all the massively more efficient means of going about things we have in our collective methodologies.
Or better, why should someone have the right to not work, when there is still work to do. This is the problem that technology is creating.
That's... backwards? The problem is that we're creating work out of aether because there
isn't work to be done for a lot of people, but we still demand that people work before they eat. Also that instead of maintaining production and reducing hours, we're either increasing production and maintaining hours, or increasing production
and reducing hours. It's really one of the biggest problems the modernized world has -- figuring out what the hell to do with all the people for whom there is no meaningful work
to do.
Technology definitely hasn't been creating more work for us. The productivity gains we've been seeing in pretty much every single field has drastically reduced the amount of effort we need to maintain parity in... pretty much any industry you want to look at.
