Dating different socioeconomic status
For example, "redneck" type of dudes tended to do well in the lower end group, while many women who were considered to be higher in socioeconomic status tended to stray away from those types.
The reason for my inquiry is that I recently read a publication stating that women lower on the socioeconomic totem pole tended to find muscular/buff men more attractive, and women higher on the socioeconomic pole tended to go for darker, slimmer types.
I don't really think that's the case, that poorer people prefer fatter people BUT, there might actually be a kernel of truth in that.
In Western countries, poorer people tend to be more overweight on average, as well as rural folk, while rich people tend to be slimmer, more in shape. Maybe that redneck is just more used to seeing bigger women and this will influence what he finds attractive, and vice versa.
I think if any man had his pick of women, he'd choose a slimmer, tighter, more fit woman.
And the guys with the money have first dibs on those ones. Many of the ethnic groups that tend to be poorer, at least in the US, also culturally value lusher women and buffer men.
