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.
I think it was 1 percent, and they said it would never go higher. The income tax was introduced under Wilson, a Dem, around 1915, if I remember correctly. The graduated rate, I don’t know, but FDR would be a logical culprit. He definitely had one, and his top rate was 70 percent, where it stayed until Reagan. No wonder those idiots couldn’t end the depression.
