Youngsters are just not interested in the concept of a career anymore, because they know it's a defunct concept. When I left school the mantra was get into uni then get a career. Most people in my generation have now (after racking up large uni fees) been on the sharp-end of a redundancy. All our investment didn't buy us what was promised, stability, recognition and a ladder to climb.
You are lucky these days to stay 5yrs with one company, if greener pastures don't call you, a redundancy probably will.
Kids are not stupid. They know that in this kind of environment you skill up fast, get in and get out hopefully with an improvement on your resume you can leverage elsewhere. The really switched on ones don't bother with employment at all. They create a business knowing full well that's where the money is.
