Another example: the "old culture" of a job for life and a single "career" that starts with your choice of university degree is being replaced by something new. The old generation won't unlearn their ways and a sizeable proportion of the new generation has learnt that cultural norm all too well. So the old generation needs to die off and the part of the new generation embodying the old mores have to be outnumbered before a new cultural norm more adapted to the current economic context can take center stage.
