A front-page New York Times article by David Kocieniewski that is also republished at CNBC reports: "In 1970, there were 14 tax brackets for the top 2 percent of earners, with a top rate of 91 percent."
That "91 percent" figure for 1970 is inaccurate. According to the Tax Foundation, the top rate in 1970 was 70%; according to the Tax Policy Center, it was 71.75%.
Maybe the reporter just hit a 7 instead of a 6, and meant 1960 instead of 1970. Or maybe it's just another example of the Times trying to pretend that the Kennedy tax cut never happened.
