I’m extremely skeptical that well over half of NYC households are in such dire straits.
But even if that’s the case, it doesn’t say “to live alone” or “to live without government assistance.” It just says “to live.”
I don’t think having roommates or a rent-controlled apartment is so terrible that it wouldn’t qualify as “living.” It doesn’t have to be completely literal. If it meant not being homeless, I could work with that. But a number that’s more than 50% higher than the median? I don’t know what the heck it means “to live” in that case. It clearly means something well beyond what the average New Yorker actually has, but I don’t know what and I don’t know why you’d call that “living.”
