Nixon was so complicated... A unrepentant sociopath that would pretty much do anything for power, yet he created the EPA, signed the Clean Air Act, Clean Water Act, Endangered Species Act, Title IX, Consumer Product Safety and OSHA. He also signed SALT and AMB, got rid of the draft, initiated lowering the voting age to 18, ended the Vietnam war (well, after illegally helping prolong it to get elected), took the U.S. off the gold standard, opened relations to China, and took on organized crime. In addition, he also pushed the idea if a negative income tax, which was basically UBI.
In today's world, he can be considered the most productive "Democratic" president after FDR. Too bad he was legitimately nuts.
