You claim it's not about stats and yet their issue is that he didn't want to get dragged into a pointless argument over the minutia of some chart. If these hosts agree that wealth inequality is a problem, then it's an established point that doesn't need to be rehashed through arguments over a chart. Gary knows this, his audience knows this, the hosts know this, and we know this, and many are living through this. What purpose does arguing over a chart do other than to try to distract from the message? If you want a strong message that resonates with people, you have to keep it simple and straightforward.
Whether he's a grifter or not is a matter of opinion. Dismissing his message by calling him a grifter is a textbook example of ad hominem. His message is simple:
- There is massive wealth inequality.
- Wealth inequality tends to get worse since the more assets one owns, the more they can use that as leverage to obtain even more assets.
- A wealth tax addresses the heart of the problem by taxing wealth directly.
What is your issue with these key points? That he hasn't spent enough time in the chart mines? That you think he's a grifter? Clearly his method of communication has been effective in drawing attention on the issue while offering a solution and I think that's a great thing.
