They know what they are doing all right. For instance, ITER's managerial staff surely enjoys the jet-setting between Barcelona and the French Riviera. But their goals are not aligned with making progress.
That's a load of cynical and simplistic crock. Yes ITER is super expensive, and maybe it's not the best use of research money, and maybe it'll never get anywhere. But the project's aims are very ambitious, and potential payoff is huge. Saying the ITER management doesn't deserve the same perks as other management is just wrong.
