You mentioned society being trapped in a post-1960s rut (harmful philosophy)...
If you compare the intellectual underpinnings of capitalism in America to what passes off as "mainstream" economic and philosophical thought today, it's not too difficult to see where we are headed.
While yesterday's mainstream thinking was driven by innovators and capitalists, today's policies are dominated by sheltered academics and their unproven half-baked economic and social theories.
No wonder we are now being told that anemic economic growth is the new normal (central planning run amok)
You can see real world examples in the dangers of the excessive conformity that we have come to know in the modern era.
Take the frequency of bubbles for instance, a big reason is that the wisdom of crowds is only valuable if the crowds are forming their opinion independently rather than a collectively, which is basically just herd mentality. During the tech bubble 40 P/E ratios was just supposed to be a new normal (and the tech bubble is fine in practice, it was just a sign of dynamism in 1 area of the economy getting too ahead of itself but the point remains), during the housing/finance bubble it was "real estate is rock solid, it won't go down" and now you have it in several areas like education, monetary policy, stocks where people are just afraid to question what went wrong. And when they do question it, it just comes off as disjointed and ill-informed (think OWS) but the angst is real. People fundamentally understand that something isn't working anymore which is why you see the rise of Sanders/Trump types.
So when there is no individual thought and everyone just accepts the status quo as dogma, it is really destructive.
While there are many political, cultural and philosophical reasons for this, I think some of it honestly does just come down to complacency. Necessity is the mother of invention and we've lived in relatively peaceful times since the 60's, bigger homes, cars, more resources, longer life expectancy, people being better educated than their parents thus leading to more efficiency in industries like insurance, finance, consulting, accounting, etc....So you didn't really need to create new energy or transport options for the standard of living to rise. Once we beat the USSR then there was no reason real to go to space anymore, once we won WW2 there was no reason for the government to do something as grand as the Manhattan project.
I see that culture changing, slowly but I do see it changing. 10 years ago you open a financial or business publication and it was all about financialization and BRIC countries or the developed/developing world. WTF is the developed world? That is basically an admission we have nothing left to do. You don't really see that anymore. You see more about startups, innovation, how to solve complex problems. You see this a little more in popular culture with shows like Silicon Valley or The Social Network movie or the movie about Jobs. I think after the finance crash, a lot of people are waking up to the fact that the only way to true growth is innovation but it didn't get that way overnight and it won't go back overnight.
