I guess what’s confusing for me is that the “63% of people don’t pay income taxes” line is usually trotted out to say that the rich are the only ones who pay taxes and everyone is just a welfare queen or something. But it sounds like you are trying to say that it shows that tax avoidance is a real problem and that this a primarily a symptom of the rich being able to hire tax evasion specialists.

If that’s the case then there’s no disagreement from me.
