When I quit practicing law (after only @ 10 years), mostly as a prosecutor, people asked why, and wouldn't I miss it? Sure, I'd miss the trials, they were challenging, but my primary answer was "I'm tired of just helping rich people keep poor people at bay."

White collar crime? You'd think there wasn't any, based on how infrequently it gets looked into. And when it IS investigated, the law firm of the prospective defendant makes a big contribution to (for example) the Attorney General's campaign fund and the investigation is allowed to wither and die.

It could make one cynical.
