My late Professor Datuk Dr Mokhzani Abd Rahim and former Dean of the Faculty of Economics and Administration at the University of Malaya once said publicly at a UMW Seminar hosted by the late Tan Sri Eric Chia in the early 1980s that Malays do not take a serious view about discipline.
I even repeated this observation when I was part of the Senior Management at Mimos Berhad when I noticed the obvious tolerance of the indiscipline of corruption.
When these two observed truths are put together into a mental model one can understand why Umno still tolerates the indiscipline of corruption.
