$this->bbcode_second_pass_quote('', ' ')wouldnt make any drastic changes about college yet. Like quitting. Maybe change your major if you are in something completely useless.
Define Useless?
To me useless will be psychologists (hey i have a degree in that

), Lawyers (eventualy, not right away, the "Shakespear Option" will cull the herd), civil engineering (road/bridge building will go down)
I see a need for these professions that can be obtained at universities and other higher learning institutions:
DOCTORS, Herbal healers, (Organic ! ) Agriculture Studies, Vetrinary care (focus on livestock and horse), Pharmacopia (you supply the doctors), Martial Arts (think West Point, Anapolis, VMI - to keep the peons in line),
Here are some vocations I would recomend my children learn in order to thrive in a post oil age:
BLACKSMITHING! ( Ok this will be a slow start up compared to others, but making everything from knives to horse shoes to locks etc. can't be bad), Gunsmithing (can go with blacksmithing, but is a bit more specialized ), Soapmaking (shampoo!), Tailoring, Textile growing / Weaving, Sailing! (with real sails), Watchmaking/ Repair, Small Electronincs repair (YES we will have them for a long while yet, and they will be less disposable!), Jewelry making/repair (people always want trinkets, and Gold may only be allowed in Jewelry in the future),
HOUSEBUILDING ! (When all the crap made to last 30 years deteriorates, people will want something that lasts 200 years or more w/ care)
These lists can be added to and I invite others to do so!
I don't see a shortage of oil in the next 20 years as a complete EOTWAWKI (end of the world as we know it) but possibly a step back in time for the non elites. (us peons).
It is always possible that the wars over the remaining oil will result in a nuclear exchange, but that was possible all along (50's -80's etc.). IMHO this does make the stakes higher than philisophical difrencess over communisim vs. capitolisim, but who knows how it will play out.
