That's nothing, Mike. Try Habermas some day. Half-page sentences are not unusual in his works (which are quite banal, if you manage to penetrate the thick German academic style). One reason why he has become so unreasonably influential and supposedly widely read must be exactly that he is extremely hard to understand.
The Lonely Crowd is another one of those badly written (and boring) books that got extremely influential. The research behind it seems rather poor, too.
I'm afraid that's sociology for you :(
