Democracy has a severe flaw, it favors reproduction not progressiveness nor the greater good. In any nation with true democracy, a disenfranchised portion of society can win power simply by out-reproducing all other groups for a few decades. All of a sudden a Putin or an Ardogan get voted in and from then on, kiss a brighter future goodbye.
It's a broken system that needs a better alternative that actually does empower progressiveness and the greater good.
