$this->bbcode_second_pass_quote('gg3', 'I')f you need a telephone, I've still got a job, along with a handful of my pals who can make it work & keep it working.

Professional warriors: People who have served in the military will be needed to organize & manage community defense and train civilians for various roles. Conscientious objectors can be trained as medics and other noncombatant roles.
Musicians: Uninspired, you're simply wrong about this one. Music has been a cultural essential since humans first figured out how to sing. Participating in music in any number of ways, also contributes to the development of mathematical abilities. Do away with music and you put yourself at a competitive disadvantage in any field where math abilities count.
Health: Herbalists and apothecaries, and compounding pharmacists. Sorry, Uninspired, the science says you're wrong about this one too (BTW, I'm a "real engineer" with a decent layperson's background in the sciences as well, so this is not foo-foo talk). Plants are the source of most of our core essential pharmacopoiea. Plant-derived medicines will need to be standardized as to potency and dosages, and much of this will be a rediscovery and refinement of knowledge that existed in the 1800s, expanded upon by way of more modern techniques and means of analysis.
Here are a few that are not obvious but are still essential, and can be sustained in a rural-based agrarian society consisting of small farms and small villages:
Legal system: Police and/or Sheriffs & their deputies. Judges and their clerks & secretaries. Prosecuting attorneys and defense attorneys including public defenders. Wardens and guards for jails and prisons. If you believe in preserving a system of equal justice under law, and for that matter a system of justice rather than tribal vengeances, you have to keep all of these. Containment and reduction of violence over time is one of the two core essentials for civilized human society.
Essential public services: Police/sheriff, firefighting, EMT, and sanitation. All of these are related to public safety & health. Firefighting is an interesting one in terms of technology and energy, and will probably remain a priority for access to concentrated fuels e.g. petroleum, and eventually, biodiesel. The technology of waste disposal & recovery will change in a number of ways that are oriented toward short-path recycling and source reduction of wastes, and increased manual sorting of the solid waste stream; I could write a lengthy paper on this subject but I'll leave it here for now.
More essential public services: School teachers & administrators. Librarians and their admin & support staffs. Conservation and propagation of knowledge is the other core essential for civilized human society.
Finance: Banks and bankers, returned to their essential roles of managing & directing savings, landing, and investment by average citizens. Investors and investment management firms, for directing capital efficiently to private enterprises (unless you prefer some form of socialism, and that's another discussion for another day). To the extent that there are any common denominators of trade, these institutions will be necessary as repositories of stored economic value and means of directing it toward useful endeavors.
Communications networks: Communication reduces transportation. The internet as originally designed is an essential for sharing knowledge and information, and minus the huge amount of multimedia fluff presently available, can be maintained with little in the way of energy & resources, compared to any equivalent functionality obtained via printed material on paper or via transportation. Telephony in its essential form is even more obviously sustainable and was so before cheap energy.
Higher education: Where do scientists & engineers come from, eh? I trust this one is self-explanatory. Education in specialized fields is still likely to be provided by major colleges & universities, and this will mean that talented individuals will have to spend their undergrad & graduate school years away from home. However what is needed is to develop the means & incentives by which most of them can return to their home locales and utilize their knowledge locally.
Religion: Hopefully more than one pastor (etc.) per village, of differing denominations, to maintain de-facto the freedom & diversity of religion that is a key component of any free society. And, a balance of denominations is also essential to maintaining freedom for those who are not theistic, i.e. atheists & agnostics.
Exactly what kind of post peak scenario do you predict? Will there even be the human resources to devote to higher education and such as we know it? I think education will be more hands on with the nearby "expert" in whatever role you are preparing for. IE apprenticeship makes a comeback.
