@hawkeye10,
the critical flaws are:
1) the system increasingly does not need human workers and does no value them but providing work so that one can have a life is one of the primary missions of an economic system
2) our current system demands ever more consumption which is killing the planet which is carrying us
3) the current system glorifies and rewards greed, which is tearing the social fabric apart.
4) the current system is hostile to democracy at the very same time that people expect to have increasing control over their own lives
5) the system no longer properly matches rewards with value, for instance it no longer uses capital correctly and CEO's make 1000+ times more money than the guys who do the work.
