Phrases like thin privilege seem weird to me. and I noticed that leftist sre quicker to assume are sctionarcy skinny.
I whould have thought it have been the opposite? outside the west arent the poorest people skinny? not saying that weight determines you as privileged or not.
In the west, fat people face discrimination, worse medical outcomes, etc. In the US, if you're very poor, you are probably still going to get enough calories, but the cheap calories are all super bad for you and make you fat. Then there's environmental pollutants, epigenetic factors, and a bunch of other stuff correlated with poverty. The only rail-thin poor people I encounter are (a) folks who are addicted to stimulants (b) recent immigrants.
honestly I have no idea. American stereotypical poverty changed from rural to urban sometime after WWII. Bourgeois beauty standards (which result in discrimination) changed earlier: think of the skinny flapper girls of the 1920s. I suppose conditions must have changed sometime after Rubens was doing his thing.
