Notice something.
He released 10 years of his tax returns.
In 2018, Sanders’s income was $561,293, on which he paid a 26 percent effective tax rate on that adjusted gross income. In 2017 and 2016, his income was more than a million — $1.15 million and roughly $1.1 million respectively — because of the advance and royalties from his bestselling book about the 2016 election. Sanders and his wife Jane Sanders paid $145,840 in taxes last year; $343,882 in 2017; and $372,368 in 2016.
They also donated 3.4 percent of their adjusted gross income to charity last year. But the campaign was also sure to note that they also gave the proceeds from Sanders’s book, The Speech, directly to charity, and that they did not take the tax deduction for those contributions, which is why they don’t show up in the tax returns.
He's a millionaire and still wants to tax himself and everyone who makes that kind of money.
Does writing a best selling book, making money from it, and then still advocating for a high tax rate make him a hypocrite?
No.
