That's a lie. The income tax was introduced after Roosevelt left office in 1908.
And it wasn't graduated, it was a flat tax starting at 5,000 bucks and up and people were told they would only ever tax the rich(5,000 per year being extremely good money back then).Typical politician BS and look where it got us. The Roosevelt that put in the graduated tax was the SOB of a socialist FDR, and he gave us SS also.
