That evolutionists demand "fairness"... honest question. and don't throw up the obvious canard... it's too easily dismissed with morality learned in kindergarten. "God helps those who help themselves."
If you're advancing your own position you're obviously getting ahead of those who are lazy. It is a self fulfilling prophecy along the lines of "luck happens when preparation meets opportunity."
it's much simpler than that. some people direct their lives, some people wait to be directed, some salivate at the prospect of directing others, some salivate at the prospect of someone else directing others, the "chosen few" prefer not to be directed .... "Do unto..." is a good direction to be pulled and pushed ...
