You are probably right about there not being an 'imbalance', but I would like to add that just because there is an efficient market in place doesn't mean there can't also be structural problems in the society. The value of labor continues to fall as automation and machinery improves, which is why uber drivers are so cheap to entice to drive. For most people, the only thing they have to sell is their labor, and as we continue to find alternatives to labor through automation, that downward pressure on the cost of labor is only going to increase.

We really, really, need to address this as a society soon.
