"Focus on the fundamentals"

Underwood Samson’s motto, Focus on the fundamentals, essentially means focusing on the fundamentals of the capitalist system – money and business. It is suggested that Changez is not a ‘reluctant fundamentalist’ of the Islamist variety, but a ‘reluctant fundamentalist’ of the Underwood Samson sort – he finds it ultimately impossible to reconcile himself to focusing entirely on these capitalist fundamentals.
