Hmmmm so productivity has increased, yet inflation-adjusted income has remained flat. Perhaps that means non-inflation adjusted income has risen, and perhaps that means the inflation tax is where you should channel your antagonism - toward the money printing that is robbing families without them knowing, instead of toward the corporations employing people toward productive ends.
I do put a large part of the blame there. That's why I love Bitcoin, once we stop printing the wealthy will no longer be able to unfairly perpetuate their advantages and more rewards for productivity will go where they belong. As the 53% movement proves, people are working multiple jobs and still not having the full benefits one should expect for that amount of work. They put the blame for that in different places than the 99% folks, but we are all in agreement it is a problem.
