Not sure I've got any except class notes and articles in memory. But to a certain extent it's obvious; there's a greater technological spectrum that there was before, and not much that widely different between what was available at the top as at the bottom.
However to what extent is that technology vocational rather than necessary.
On this, how people are in other nations isn't really relevant. What's important is that the gap between our poor -- of whom there are increasingly more -- and the rich.
It's feudalism we're heading toward -- corporate feudalism, to be specific. Feudalism is a sort of oligarchy, though of a plutocratic sort. The difference is that the few rule different fiefdoms within the whole; a recent example in history was the Third Reich, where all the different aspects of the regime had different leaders who treated them as private preserves -- part of Hitler's task was keeping them from literally going to war with each other.
I don't think it'll be a truly feudalistic system because I really doubt we will have serfdom if this progresses forward. However I do agree that companies if allowed to be as they are could grow to the point where they could conquer small countries.
If I could get away with it?
Take half the wealth of everyone worth over $5 million; use it to pay down the debt (I can't get any solid figures on just how much that would do). Then make a tax structure sufficient to reverse the upward drift.
I once read a statement by, IIRC, Warren Buffet to the effect that when you get down to it, if the top 2% in the country were suddenly stripped of the majority of their wealth, most wouldn't feel more than a brief annoyance, because for those who just like enjoying great wealth, there would be no change in their ability to do and spend as they pleased, while for those to whom it's all about the numbers, they'd just adjust some decimal points and keep playing.
I don't like that, philosophically, but without some even more radical social change, I don't see much else that could be done. In fact, personally I'd rather see more radical change, beginning with instituting a rational basis for land ownership......
