So let me understand that ProPublica is calling a "true tax rate" as the rate they paid income taxes divided by the value of wealth? For instance I'm having a hard time reconciling this paragraph. "In that year, Bezos, who filed his taxes jointly with his then-wife, MacKenzie Scott, reported a paltry (for him) $46 million in income, ..." That year reported $46MM in taxes yet the article keeps claiming the Bezos earned billions a year. I believe the article is conflating reported taxable income and wealth. The US tax system is based on taxable income and wealth is a totally different asset. I suppose the article writer is proving the difference in rate of taxable income vs wealth but that same comparison needs to be done in all other income brackets as well. Perhaps I'm missing it but I'm not seeing the "true tax rate" across different household income profiles.
