Why do we still have ugly people?

Why do we still have ugly people? You'd think that evolution would try and kill off anyone with an undesirable/unlikeable trait right? But, still we not only have ugly people, we also have unhealthy and stupid people [especially humans]!!

So are beauty, health and intelligence overrated?

I mean if evolution were to pick and choose the traits in humans for a better race. After all, we have been around for about 200,000 years [http://en.wikipedia.org/wiki/Homo_sapien]. That would mean that evolution would still have a minor effect on us and we would be getting more and more beautiful, healthier and more intelligent. [Isn't that what most of us strive for - to be more handsome [beautiful], healthier and fitter and more intelligent?] So, let's look @ what evolution really has done to these 3 traits...

Beautiful - apart from the receding hair present in humans, beauty is really open to debate!

Healthy - our dying age has increased, but a healthy life is open to debate!

Intelligence - ok, let's not even go into this right now!

So, what has evolution decided that would naturally evolve from humans? Or well, are we just not intelligent enough to look for that trait, which has evolved?
