But peacocks grow their own feathers and are not subject to marketing propaganda put out by capitalism.

What they're attracted to is both naturally created and naturally occurring.

I'm not talking about the drive for sexual competitiveness, I'm talking about what is actually on display.

I assure you that what is naturally biologically driven does not follow fast fashion trends, will have limits, and be kept in check because it has to balance against survivability.

A peacock who grows too extreme a tail will be picked off by predators. A deer who grows too extreme an antler rack will not be able to move through the woods or even get trapped in tree branches.

A female bird with flashy plummage will not be as able to successfully fledge a clutch if eggs as her more color muted counterpart.

Sexual display, when naturally occurring, has limits and will be naturally driven.

What we humans have, is not that. The desire, born of the natural world, is still there. But the extremes of expression you see are not.
