Nixon believes the Keynsian nonsense. And instituted things like wage and price controls.
It needs to be remembered that Ronald Reagan received his economics degree BEFORE the New Deal economic theories took hold. His was a classic Adam Smith Wealth of Nations education.
Contrast that with George H.W. Bush, who also had an economics degree, but received after WWII. That’s why Bush called Reaganomics “voodoo” economics, because he was never taught about the “invisible hand,” etc. And why he could be talked into tax increases. And Bush was also a Nixon protege.
Trump at the Wharton School probably received a more classical economics education, and decades in business taught him how economies really work.
These two schools of thought, one based on reality and one based in theory have been battling it out since the New Deal.
Some conservatives like Pat Buchanan and Roger Stone are Nixon fans.
