I'm living in NoVa in a zip code in the top 2% of wealth in the US. (Sadly, I'm not
personally in the top 2%, I just rent an apartment here.) There are McMansions all around, and they are hideous. There's no sense of design or symmetry. And this is no aspirational neighborhood--if you're buying one of these houses, you are already at the top of society.
As much as I hate looking at these McMansions, they do give me one consolation: money can't buy taste. Maybe I'll never afford that monstrosity you call a house, but at least I've got the sense to not want it in the first place.
