“The doctrine of equality! There exists no more poisonous poison: for it seems to be preached by justice itself, while it is the end of justice” Friedrich Nietzsche
People always fighting for equality, in terms of gender, racial, economic status, etc.
But the world never been to their favor, the world never been in equality.
Communist try to make everything equal, same wages for all the jobs.
But they failed, with everything equal then no reward for somebody doing better than the rest. This condition will make a capacity lid. No need to work harder or smarter than the others. Everything become stale. No growth and ultimately died.
When a society respect differentiation, hierarchy of performance. Then it will create competition, with competition people try to be better than the others. Trying better means force people to perform better everyday.
This will make growth, economic expansion, better living, better education.
