allgoodnamestaken: you absolutely have several very good points! I fully agree that, on average, this generation of engineers is failing the next generation- on many counts.
We do see the same pressure here from the engineering regulatory bodies to increase the academic requirements for licensure. These same folks encourage increased engineering enrollment and expend a lot of energy recruiting kids into the profession. They fail to differentiate between the benefit of engineering to society (which is indisputable) from the benefit of engineering as a career choice (which is very disputable!) or the need for an increased supply of engineering graduates (which is beyond dispute- we are drowning in them already). That said, we see pressure in the opposite direction, to drop the experience and mentorship requirements from licensure for fear that it is acting as a barrier to licensure, and hence employment, for foreign-trained engineers and fresh grads. In my opinion, that would be an opportunity to take our flawed professional license and make it utterly and completely meaningless.
Absolutely, working engineers should be more diligent in carrying out their responsibilities to the next generation of engineers- in many, many ways. Our regulatory bodies fail us in this regard. To be fair, working professional engineers are suffering under the yoke of a regulatory environment which puts on them additional responsibilities arising from their title, without meaningful matching benefits arising from that title- and they are doing precious little to change that either. Here in Canada, and particularly in Ontario, a licensed professional engineer is granted no meaningful rights arising from their license, that do not require an additional "license" to take advantage of (i.e. a certificate of authorization), or cannot be obtained by a "legal" cheat of the system (i.e. by working in an industry considered "exempt", or for an employer with a C of A). So if you're concerned that the experienced engineers are failing in their duties toward the next generation of engineers, I'd argue that they are also failing in their duty to defend their own generation as well.
Regrettably, we engineers are too timid, and too concerned about perceived conflict of interest, to pursue our own self-interest through effective advocacy. So what we have here in Ontario is an advocacy body which stays silent about the oversupply of engineers to the marketplace (i.e. they are not doing any effective public communication on the matter, though they may be talking quietly and privately with various levels of government without mentioning this anywhere publicly), while at the same time advocating "continuing competency" requirements for people already having a license, and threatening students with refusal of admission to the advocacy body if their Frosh Week activities get out of line (a power they do not have). They don't understand their role- they think they're an extension of the regulatory body! I helped found that advocacy body, and am dismally disappointed in the result: it has utterly failed to live up to its mandate, though there have been a few hopeful signs along the way.
I don't blame students for seeking engineering as an educational choice. I blame educators and engineers both, for failing to point out in a meaningful way, that an engineering education is no longer any guarantee of an engineering job- and that those who seek an engineering education and do not end up with an engineering job, are not all patent lawyers and CEOs either. Most of those who fail to gain entry to our profession upon graduation, have not sought other employment by choice, but rather by default.
