While in the political wilderness, Mahathir wrote his first book, "The Malay Dilemma". He set out his vision for the Malay community. The book argued that a balance had to be achieved between enough government support for Malays so that their economic interests would not be dominated by the Chinese and exposing Malays to sufficient competition to ensure that over time, Malays would lose what Mahathir saw as the characteristics of avoiding hard work and failing to "appreciate the real value of money and property". The book continued Mahathir's criticism of Abdul Rahman's government, and it was promptly banned. The ban was only lifted after Mahathir became prime minister in 1981; he thus served as a minister and deputy prime minister while being the author of a banned book. Academics R. S. Milne and Diane K. Mauzy argue that Mahathir's relentless attacks were the principal cause of Tunku Abdul Rahman's downfall and subsequent resignation as prime minister in 1970.
