I honestly and truly believe that almost all the inefficiencies can be attributed to meddling governments and political entrepreneurship of anti-competitive companies. I recognize this is a minority view, but I am prepared to argue it.
let's move this away from generalities, which are all well-hashed arguments on both sides, and focus on the specifics that we see in the global market today.
for instance, how is the poverty trap created by Walmart-esque wage suppression coupled with high unemployment rates attributable to governments? how is the large environmental externality of shipping and manufacturing attributable to governments?
the short answer is: they're not. but i'm sure you'll give me a longer answer

I can attribute those problems to a growing money supply, it is the single biggest cause for labour inequality and disregard for the environment. While governments allow fraction reserve banking and control it through a central bank they they are in all reality controlling it.
I'd argue nature does a better job at finding Homeostasis than ignorant power hungry egos of men.
