Why?

Why is there so much inequality in the world? Why are some healthy and some ill? Why are some rich and some poor? Why are some brilliant and some not? Why are some developed and some underdeveloped? Why? Why can't we all be equal, happy and rich? Mind you, all mentioned is not my definition of happiness!!!! My definition of happiness will include the love of God, love from my family and friends and perfect health. What is your definition of happiness?
