"Is there a stronger word than hypocrisy? Because that doesn't seem quite adequate."

Three words, actually, one of which I'm sure you and others here might deign use. But I worked in engineering for much of my life, in close contact with the men and women who are the true wealth-creators - the shop-floor workers - and I'm no stranger to, nor squeamish about using, their language. The phrase that immediately springs to mind is 'Self-serving arse-holes'.
