Any system depending on help from an invisible man in the sky is fucked from day one.
Capitalism is just like socialism...they're both segments of a balanced economy. No matter who wins in 2020, we're still going to have both public and private sectors, ie, socialism and capitalism.
What we need to catch up to the civilized world is a more comprehensive public sector and a more regulated private sector--in other words, a little bit more socialism. Otherwise, we're a full blown third world banana republic within a couple more generations at the most.
Human beings are just one of the more advanced (except for Republicans) species in the animal kingdom. We're not spiritual beings naturally looking to do the right thing. We're not even as good as dogs at doing that.
We depend on collective needs as a society to be motivated into doing the right thing. In other words, what's bad for the common good must be discouraged on a societal level. Political conservatives and evangelicals do everything in their power to get in the way of that dynamic. That's why intelligent people must prevail over them.
Where I think you and Jarod are both right is that capitalism is more efficient to improvise throughout the supply chain, at every link, if you will. A managed economy
is stultified and resistant to change. That, to me, is the "invisible hand " metaphor. And your part about great problems requiring great solutions I also endorse.
Behaviors can't be modified as smallball, we need systemic carrots and stick that can only be practically and ethically provided by democratic governments.
