I think it is just that evolution is sooooooooooo verrrrrrrrry slllllllllow so that we wouldn't notice any evolution in several human lifetimes.
It is also hard to figure the nature / nurture componant. So that humans are getting progressively taller, for example, though that may have more to do with better nutrition (in general) rather than evolution of genes.
There also isn't such a fight for existence as there once was. I mean, we don't compete for scarce resources quite the way we used to. And then medical advances deal with conditions that would have been selected against in the past.
