A Question about Hiring Practices

Once again, I was leading a dialogue about hiring people. And once again, it was a group of baby boomers in management roles. And once again, the position of most of the room was the same.

"These generation Y people (30 and under) are lousy hires."

"They expect the world to be just given to them."

"They don’t get that they need to earn their way."

Then, the question suddenly appeared to me. Why is it that the generation who said, "Don't trust anyone over 30," now refuses to hire anyone under 30?

Thoughts?
