That is the most interesting aspect of these articles. They are optimised for the title, not the content. Ignore the oil spill: if you lose $100m, you won't pay tax on that..."Billionaire pays no tax" is a better headline than "Billionaire loses lots of money". If you think that a wealth tax is a good idea, fine just say that...don't bother with the article. But the reason most journalists don't write about wealth taxes is because they lack the actual knowledge to understand why we don't have wealth taxes, they just write misleading bullshit about income taxes instead.
This isn't just splitting hairs either. There is enough real information on inequality in the US (this is something that most journalists are very clever about...this is an article about inequality because journalists know that the target audience will interpret it that way). You don't need the bullshit articles. These articles misinform the public, they don't need to be written.
