Get rid of Capitalism and replace it with What? What other system has ever produced truth, justice and food for all? Or even a close proximity of a productive economy with surpluses of food and products? Where is the model you think the world should turn to that exists in the real world and not in the pages of some manifesto.
Periods and civilisations when populations were allowed to thrive and express themselves without running into resource constraints or dabbling in conquest (military or economic).
Hmm. Early Islamic cultures were quite good at the academic freedom bit. Mostly based on opening up new trade routes, with money lending with interest a capital offense. Not be confused with the more extreme Islamic trends we see today, it was at the time a stabilising influence and a set moral values which were held up above the petty squablings of the ruling classes.
A bit like the monestry movements of early medieval Europe. They were so good at being poor and hardworking and reliable that they ended up immensly wealthy and corrupt and greedy. C'est la vie.
Bhuddist societies have always been a more stable and environmentally friendly in practice. An emphasis on satisfying 'spiritual' needs with as small as possible impact on the 'natural' world.
Polynesian societies managed stable and relatively strife free societies for centuries on extremely limited resources. Basically stone age tribal monarchies, the very visibly finite resources concentrating the mind wonderfully. If you were young and ambitious you set sail into the big blue and hoped you hit land before the water ran out.
Scotland in the reformation has a reputation for hard working industriousness, but the underlying source of that progress was a mixture of fossil fuels and an expanding economic empire with lots of slavery.
There are plenty of alternative economic systems. Share cropping, medieval common land, etc. etc. Which will work best depends on the local geography and resources available.
