You can watch roger scruton's sublime documentary "why beauty matters".
As a counterpoint demoralization includes making sure we are surrounded by ugly art, ugly buildings, ugly statues. When everything is ugly, people are demoralized. They don't feel the need to defend and protect their culture. And if they don't, it's easier to take everything from people.
If you go to art exhibits by students you can see this in action very clearly. You see the booklets informing you why beauty should never be the goal of art (covert message: beauty in art is bad). You see the ugly creations of the 4th year students. And it actually starts looking better when you go down to 3rd 2nd years. Then there's the first year creations, which generally are close to beautiful. They look like the untrained, slightly amateurish creations, but definitely from talented kids. You can see how their goals are realigned and how ugly the education is making their creations.
This obsessesion with the ugly becomes unconscious. And I'm sorry for anyone that has vitigillo, but it's very ugly. Beauty isn't the only thing that matters, but the truth is that it's ugly. Like being fat. They'll deny that this is true and claim its about inclusivity and body positivity, but even in their hearts they know that isnt true.
