Point being capitalism is not a system....it is THE natural system. All else is a hinderance to it.
If you can't defend it or feel it is safe then capitalism fails because people hoard instead of spend.
This is why almost all other group/pack species in the animal kingdom all have a central leader, because............ it's not the natural order of things. The idea of people being equal enough to contribute is only a recent concept to be fair.
That's not a bad problem, but it's also worth recognising that we've got to think of our social structures to keep pace with the great things technology is doing for our lives.
