Why does /pol/ care about race but not class?

When you have walkable cities, you force women to walk. Women forced to walk will lose weight naturally and stay skinny and fuckable. Women forced to walk outside will want to dress up to signal their sexual value, thereby buying luxury clothes. Skinny fuckable well dressed women walking outside all day will attract ambitious simping males with increasingly elaborate methods of seduction, leading to increasing levels of culture and class.

Class. Culture. Skinny fuckable women in beautiful dresses outside all day. You could have all of this.

But not without walkable cities.
