It Was Not the 'Biggest Tax Cut in History.' By the Standard Measure, It Was the 8th.

Trump called the 2017 Tax Cuts and Jobs Act the largest tax cut in US history. Measured as a share of GDP, the standard metric, it ranks eighth since 1918 (fourth in inflation-adjusted dollars); the record holder is Reagan's 1981 cut at about 2.9 percent of GDP. The 2017 law cost about $1.45 to $2.4 trillion over a decade; beating 1981 would have cost roughly $6.8 trillion. Marcus rates it False.
