Nixon's price controls did not work. Saying "arguably" doesn't change that. Most reasonable people aware of the history of the 1970s would expect more thorough support for such a controversial assertion. It's like saying "Pol Pot was arguably one of the 20th century's greatest humanitarians." If it's arguable, let's see you argue it.
OTOH the price controls and centrally planned economy we had during WWII transitioned this country from the hardships of the great depression into the much better standards of living enjoyed during the years following.
I used the word arguably because this is clearly debated territory, for obvious reasons. Prices stabilized after the controls, though the policy was held for longer than it should have been.
