For 18 years of my life, drug addicts, alcoholics and rehab facilities were only things I saw in movies. Depression and therapists seemed out of my world.

The walk eastward from the Penn campus to Center City is, as Penn President Amy Gutmann put it, "ugly."

If corporate ethics start in business school, the industry landscape of the future could be even more scandal-ridden than it is today. A recent study found that business students are more likely to cheat than any other graduate students, though some at Wharton doubt that the data apply to Penn's MBA students, saying that the school's emphasis on its Code of Academic Integrity tends to discourage cheaters.
