Humans change very very slowly.
Did you know that bananas are the number one fruit sold in the world?
We  are  basically  still  monkeys...
It will take hundreds of thousands of years before we evolve some more.
Well, unless we geneticaly modify ourselfs. The question is, what will those changes be?
If people will change themselfs to be more greedy bastards then no, RBE can't happen.
For RBE, people need to be more cooperative and less selfish. This is a chance noone will take freely.
