[E]ngineers are trained to sit down and figure out how something works before busting it. Lawyers are trained to bust things efficiently for a high tab. There is a fundamental difference in world views....I had been thinking of something similar.
My mediaevalist mind goes immediately to castles. As an analogy, lawyers are trained in the attacking and defending of castles. This is not a bad thing, as defending from attack is what castles are ultimately for. To defend well, you need to think like an attacker. To attack well, you must think like a defender.
But neither skill has anything to do with building a castle, which is a separate skill. In terms of business, military, trade, and the other important skills of building, it is worth noting that lawyers know nothing about making any of those things. They can attack them and defend them. What we eventually come to is an endless round of attacking and defending castles, with no one building any new ones.
