I'm still unconvinced that many of our problems couldn't be solved with some innovative tax solutions. I see no reason that this tech revolution should be any different than any other in the past (i.e. it increases economic opportunity for the vast majority of people over time), but 4,000 Uber employees making boku bucks while 2,000,000 Uber drivers starve is an invented problem, and thus can be solved by invented solutions. Wealth is filtering upwards for a variety of reasons, but the onle thing all of those reasons have in common is that the law currently allows or even encourages it. Laws aren't immutable. What we need more than anything is bold, new political leadership (on BOTH sides; as crazy as GOPers are, Dems are ossified dinosaurs who need to go away fast).
Key phrase: over time. If you fear technology, you're a Luddite. If you're a Luddite, you were a protected trade at the turn of the 19th century that saw their profession destroyed. And lo and behold this led to mechanization and a growth of output and the whole of the modern era etc etc. It also led to 120 years of Dickensian nightmares and a slum class unprecedented in Europe. Everyone fawns about the Victorian era without paying lip service to the nasty, brutish and short lives of the 95% of people who lived it. The problem with invented solutions is they have to be implemented and they generally don't favor the rich. And, as the rich tend to make the rules, they aren't immutable per se... but the natural tendency of culture is towards a Dore woodcut of hell.
