There is also the issue of circumstance to consider here. The world we've grown up in is much different than the world older folks grew up in and the older generation doesn't always recognize that. Many of us were raised with the old adage that if we worked hard and got a degree, success in life was 'guaranteed', though this has been and still is shortsighted. While that sort of path worked in the past for many, the job market right now is so saturated, and the culture has driven itself to the belief that it is the piece of paper that is important, rather than the education we gain, are the major issues at work in our society.
The journey one takes, the mistakes one makes and how we apply our learning is what matters more, and it always has, but both the young and old don't always recognize that at first, and sometimes not at all because their predecessors often had a hard time understanding it themselves, as their perceived 'success' in finding a career and a life was based on a limited understanding of circumstance and timing. They obtained their degree, and thus they were hired, therefore believing the degree generates 'success', rather than how we use the education instead (and this includes the present hiring market today as most of them are of that generation. How many times have I heard people spout off the belief that a liberal arts degree is "useless", when it often provides a much broader education and world view than a particularized degree with its own unique skill set. It'd be a grand thing indeed if we could manage to combine both a liberal arts education and the education of said particularized degrees into a slightly longer and potentially cheaper program. One would think that humans would place the strength and growth of the species as the ideal over the exploitation of each other, but I digress too much).
Thus the ideals that applied 10, 20, to 50 or 60 years ago are passed on rather than the older generation recognizing the present situation as a new and different playing field with its own unique set of rules and opportunities. There is very little to ponder on why the younger generation of this time is much more apathetic than any other one previous. We were raised to believe that we were entitled to life, and that feeling cannot be fulfilled in the same manner as our predecessors. It's not something that can be told of course, it has to be learned on our own, otherwise it has no meaning to us individually.
Hard work is still going to be a factor in finding 'success', however you define that word, but ageism is if anything a great sign of the immaturity of the human race and how far we have yet to go.
