Query: Sean has a big chip on his shoulder

I put this book down after reading the first half. Theinsights into the upper levels of SF society were interesting,but Sean's perspective really soured the experience. It sounded as though Sean had an upbringing superior to most, includingextreme privilege and decent support from his parents. Hisresponse is a whining stab in the back. I wonder how he'd feel ifhis son did the same.
