The top 1% globally probably includes a good chunk of upper-middle class Americans (at least in the classic definition of upper middle class, maybe not in the informal “median income” sense that sometimes gets used). We like to point our fingers at private jets because they are particularly extravagant and we only need to take them away from a couple people, and they are a problem. But also heating McMansions and pushing around suburban SUVs ought to be avoidable.
