Why are women attracted to scumbags?

I am 39 now, I never had a girlfriend, nor a relationship. I have been told that I am a "nice guy" but women for some reason hate nice guys! I have a job and a car, I take care of myself.

but all the time I see hot women, and they hang with guys who can't hold on to a job for 2 months without getting drunk or high, and then beat the crap out of these women. but for some reason I can't fathom, women prefer scum vs a genuine nice guy who is ready to please here and put her first.my question is .WHY WHY WHY? and please. Don't say "not all women are like that. remember I am 39.I have Experience that says otherwise.
