You are disparaging people who are not as knowledgeable as you (elitist); they didn't design the homes, nor approve the development, nor set the zoning. Their casus belli is that they are wealthier than you, and unaware that they're buying the wrong kind of house.

Making fun of rich people for buying stupid stuff isn't punching up; it's making fun of their ignorance, regardless of whether they have more or less money than you, and can be equally applied to poor people making poor purchasing decisions.
