I definitely agree that for a startup, it's better to hire someone who's looking to step up and build the business, not looking down to grab some equity.

However, I don't think someone's résumé is the only way to determine whether someone is looking up or looking down.

There are plenty of experienced guys who have been there, done that, but are looking to accomplish something really significant. These guys are perfect for startups because they're just as interested in achieving lofty goals, plus they already have money to support themselves.
