There may be an argument about how the two are linked, but the -ism on display in the second photo is racism. The US built the suburbs quite explicitly to keep black people out by using poverty as a proxy, after the SCOTUS blocked housing segregation.

I think that you missed the point the post is making, which is that it is ironic to claim that capitalism saves us from having to live in drab cookie-cutter housing given what suburbia looks like.

You don’t have to live in those places. You choose to.

Can’t pay me to live in one of those.
