Why don't humans have proper hair?

And another thing. Humans don't have proper hair. They are, to put it baldly, more or less bald. If you look at them they look a bit like Chinese hairless dogs. There's a top knot of kinds, a bit of hair between the back legs, some under the front legs or armpits, and then a tiny scattering on the chest with the males. Males have a bit more body hair but their top knot goes manky in old age and sometimes vanishes altogether. Human hair also fades with age and eventually goes white. It seems to me absolutely mad to wear your hair at the crease where the leg meets the body. Most of us cats have a less hair there rather than more.
We cats vary, of course. There are the sleek short hairs like me, gleaming black all over except for a very tiny two or three white hairs on the chest. Then there are the long haired beauties like Catherine in the photo. And the semi-beauties like elderly William my companion. He is semi-longhaired with shorter tougher hairs on his back. Finally there are cats like Dragonheart (see last blog's comment from her domain at http://dragonheartsdomain.blogspot.com) who have no hair at all. She doesn't have ridiculous tufts of hair in her armpits. The result is far more beautiful than the bald but tufty humans.
The way feline hair varies is due to humans. They have selectively bred us for long, or no hair at all. They do this by restricting our right to choose partners over several generations. They bang up stud cats in a chalet to make them service females which are not chosen for them. Sounds good? Well it isn't because most of the stud cats sit around in their pens with nothing to do but occasional sex - no hunting, for instance, little human contact. It's a deprived life. They'd get much more sex, with partners they chose, if they were allowed out onto the tiles like the feral toms.
If humans can do this to cats, why on earth don't they selectively breed themselves for better hair? They would look far more attractive if they had short glossy fur all over their bodies like me, long hair like Catherine's or even be properly hairless all over like Dragonheart.
instead they have these pathetic tufts. They fuss endlessly about the tufts on their head. They brush, comb, fluff out, shave it all, cut it, dye it, condition it. But they're not willing breed selectively in order to develop nice glossy all over fur.
No sense at all.
