With regards to your last point: it's also up to job seekers and employees to signal to organizations that they need to take professional development seriously. You have to fight the pressure to over-specialize and demand opportunities to learn new tools and techniques. There's a basic conflict of interest here between employer and employee: the employer wants a highly specialized cog they can replace when their needs change. The employee wants to develop a speciality, but also build a general base of skills and dabble in new technologies so he can stay employable for years down the road. Employees need to fight for their interest in this regard, and employers need to have the foresight to realize that the most talented people who have the most options will not take a job at a place that stifles their professional development.
