I hugely respect science per se -- but scientists and most other types of intellectuals are typically people stuck working in a bureaucracy.
Working in a bureaucracy induces a particular type of thinking on an individual -- I call it statist thinking -- that bureaucracy is not evil (note: it is), that difficult decisions should be made through careful deliberation and possibly collaboration with others instead of on your own (a precondition for groupthink and a bad quality in an executive position which by definition requires a degree of mental toughness). People who got rich and successful outside of the bureaucratic system often become an object of envy by people inside the system, even if they will consciously deny it, which then leads to the perverted notion that the only way to make the world a fair place is to increase the reach of the bureaucracy.
Now, America was founded by intellectuals (though not of bureaucratic kind). The thing that distinguishes America from most other countries in the world is that in America one specific type of freedom is respected: "freedom to rise". In the old Europe people at the top were often members of aristocracy and it was obvious to everyone that they didn't have to work as hard as everyone else to get where they are. In America, people at the top were often (though I admit not always -- just more often than in Europe) the hardest-working, smartest, and toughest-minded individuals, and it was obvious to everyone that they got there on their own. Bureaucracy, in a way, is a lot like aristocracy (actually it is more like a medieval guild system), since it has its own system of ranks, and you can't easily get from one to the other just through working hard -- it has to be "bestowed" on you. Hence why Americans tend to disrespect bureaucracy, and, by the way, that is a very good thing.
