Are people flaunting, or are they participating in a discussion about affordability of housing while you interpret them as flaunting? I only ask this because I've rarely seen people here outright flaunt/brag in the original sense of those words.

There's a difference between:

"Doesn't matter to me, I can afford it lol, sucks for people who can't."

and

"I pay X for housing and get paid Y in salary and that's why living here makes sense for me."
