It is still logical for someone of any tax bracket to advocate for raising tax rates, while paying their owed taxes and not paying any more.

> Hard to take him seriously when he doesn't himself pay more tax

Why? Advocating for a change doesn't imply that you need to act like that change has been made already.

For instance, I am a huge advocate for building out more sidewalks in my city. I don't currently walk everywhere, though, because the sidewalks today aren't suitable for that -- the change needs to be made first.

Likewise, I could donate all my spare money to the city to fund sidewalks, but this goes against my visceral sense of fairness: I am advocating for my local government to build sidewalks, not saying that sidewalks should be built by any means necessary and that I'm willing to foot the bill alone.

Sure, in that “the world needs less murder” remains a good point even if it’s a murderer saying it.

I’ll take the billionaire who advocates for fairer taxes over the one who doesn’t, any day.
