No, it is fact that in many cultures, light skin in women was deemed more attractive due to a class thing as it indicated that she did not work out in the sun
And in other places and times, a nice tan was considered attractive because it meant that the person had the resources to afford outdoor leisure time instead of being stuck working inside.
In some times and places, being fat was considered attractive because it meant the person had ample access to food and didn't have to do a lot of manual labor. Elsewhere and when strength and "fitness" are considered attractive because they mean that someone has the time and budget to afford to go to the gym regularly and to choose what they eat based on how healthy it is.
Congratulations, you have discovered that people are attracted to signs of wealth and social status. In some times and places, that has included fairer skin for a wide variety of societal reasons, but that's exactly what the reasons are: societal.
