...Capitalism doesn't need to exist. What need to exist is
  the human race. Capitalism might as well be a byproduct of
  our rapid technological advances comes with industrial
  revolution.

What alternate system would you put in place that has fewer ills that has not been tried before?

  Capitalism is a tool we devised, now it has probably 
  fulfilled its destiny, at least for that time being. And 
  the focus of global governance should shift from being the 
  economical winner to co-exist peacefully and sustainably 
  in a controlled way.

And do you expect the developing economies who stand to greatly benefit from the continued primacy of capitalism as it exists right now, to consent to some new untested system?

Keep in mind they are just entering the phase when they can expect to greatly benefit from their favorable demographics while those in the West are facing decline.

Do you expect them to willingly come on board this new economic deal, that the West proposes? Do you see no conflict of interests?
