Why do you think high taxes and "safety nets" are the way to go? Why can't we just be free? How many times must collectivism be exposed for the fraud that it is before we stop re-visiting that waste of time?
And that's just the actual jobs, with automation eating more jobs ever faster, fewer workers are now producing more than ever meaning there are fewer salaries doled out and even less money making it away from the wealthy.
Communism did fail, but I think it arrived too early. I really think there's some merit to the idea that once the machines have eaten all the jobs, and once we're free to our own time, that there's no reason to keep up the illusion that we must remain employed for seemingly little reason other than "that's the way it's always been done."
We're going to have to wait until the baby boomers die off to have any reasonable chance of getting a proper safety net in place.
