So there are all of the capitalist models that don’t work and all of the non-capitalist models that don’t work.
The difference is the capitalist models are doing what they are intended to do whereas the non-capitalist models have failed for all sorts of reasons.
Better to try a fairer, non-capitalist, non consumerist model and get it to work that continue with models that bring about massive inequality as a key part of their approach.
Of course, people would need to realise it would be good for them and understand why – looking at 2016 people are not very good at that….
