> So what's your point other than trying to argue over the definition of poor?

Because people make political decisions about programs that support the "poor" and the definition matters.

In particular, if a program supports the "poor" and winds up handing money to someone who is making $100K, there are a lot of people who will scream about that and attempt to cut off all support for all poor people.

This was the whole the point behind the racist "welfare queens" dog whistles, for example.
