The kind of people that have the abilities and desire to "change systems from within" are very different from the kind of people that are good at "making better systems from scratch", or "making new systems in places with limited resources". Dealing with complicated peopleware meshes and solving resource reallocation problems is a completely different problem from surviving and thriving in a harsh environment with limited resources. The people needed to solve these types of problems think and see things very differently, they never get along with each other, and I'd imagine that if an alien psychologist would visit our planet, (s)he could literally consider them different species!
