Huge problems, including building sustainable energy and transportation systems. Huge underutilized resources (unemployment). It looks to me like casino corporate economics (based on short term “casino” speculators and profit-seeking leviathons in an economy based on limited resource scalping and world-destroying externality dumping) has brought us to the precipice with inertia that looks unstoppable.
Looks to me like this jig is up. Start thinking in terms of command economics.
