 In the Menzies Government, McEwen pursued what became known as "McEwenism" – a policy of high tariff protection for the manufacturing industry, so that industry would not challenge the continuing high tariffs on imported raw materials, which benefitted farmers but pushed up industry's costs.This policy was a part (some argue the foundation) of what became known as the "Australian settlement" which promoted high wages, industrial development, government intervention in industry (Australian governments traditionally owned banks and insurance companies and the railways and through policies designed to assist particular industries) and decentralisation.In 1958, following Fadden's retirement, McEwen was elected unopposed as leader of the Country Party.
