Look at this sentence in the Propublica article:

> No one among the 25 wealthiest avoided as much tax as Buffett, the grandfatherly centibillionaire. That’s perhaps surprising, given his public stance as an advocate of higher taxes for the rich.

It is clickbait, emotion inducing garbage. Buffett’s stance for higher taxes has nothing to do with the fact that he had less income than other rich people.

I expected better from ProPublica. Arguing for taxing unrealized gains is fine, but trying to make it seem like Buffett is doing something sneaky to churn emotions is bullshit writing.
