"people who were just born with attractive genes"
Have you ever met someone who seemed naturally good looking? Usually they care a lot about clothes, accessories, and are passionate about style and appearance. One guy I know always enjoys going "thrifting" at secondhand stores, and is incredibly enthusiastic and helpful if you go with him. So his success is related as much to work as it is to luck.
There's a lot that goes into being attractive in the same way there's a lot that goes into being "smart" (e.g. someone with a phd may be born smart but they worked incredibly hard to earn that phd).
