Why do millennial guys want to only date 20 year old woman?

I am not jealous just wondering why do 20 year old woman think their so good looking and great? A 20 year old woman sure still has daddy paying her phone and car and not yet have a real job. Older women are way better established we know how to cook clean. Seriously what the hell does a 29 year old see in a 20 year old woman that isn't wife material?
