They’re a bunch of thieves and cheats:

The survey found that 35 percent of boys and 26 percent of girls — 30 percent overall — acknowledged stealing from a store within the past year. One-fifth said they stole something from a friend; 23 percent said they stole something from a parent or other relative. …
Cheating in school is rampant and getting worse. Sixty-four percent of students cheated on a test in the past year and 38 percent did so two or more times, up from 60 percent and 35 percent in a 2006 survey. …
Despite such responses, 93 percent of the students said they were satisfied with their personal ethics and character, and 77 percent affirmed that “when it comes to doing what is right, I am better than most people I know.”

Separately, Naomi Schaefer Riley discusses a trend among married 20-somethings:

In 2006, about 19% of married men and 13% of married women under the age of 30 said that they had been unfaithful to their spouse. Do those numbers sound high? They certainly are if we compare them with the results of a survey 15 years before, when the respective numbers were roughly 13% and 11%. A “mere” two-percentage-point increase for women and a six-percentage-point increase for men may not sound like much, but to put it another way: Between 1991 and 2006, the numbers of unfaithful wives under 30 increased by 20% and husbands by a whopping 45%.
