Agreed wholeheartedly. Some of the nontrads I've met so far were bartenders, construction workers, meter maids, firefighters, and the list goes on.
In fact, I've only one thing that could possibly work against nontrads...disclosure. Some schools require disclosure of things that I can't even imagine why it even matters other than the state board of bar examiners thinks it matters. The older you are, the harder it is to remember every bloody speeding or parking ticket you've ever had.
