I'm not sure you're going to be satisfied with my answer on this, because it won't be exact answer on your question, I'll have to answer in my style.
I would answer with another question (just like politicians :-) )
How long we, the people, will put huge efforts it destroying each other freedom?
How long we'll have a need to put down someone else, in order for us to feel better?
How long will greed, selfishness and ego rule our lives and make us do terrible things to other humans?
