<The real solution> I agree 200% with everything in the post except for the allocation. If stock and bond performance are not directly correlated, and stocks outperform bonds, I'd go with a 33/66 split, but since many stocks have bond-like qualities the 25/75 split is reasonable. Why not buy the Wilshire "total market"? I'd put 5-10% in gold and 10-15% in international funds (as long as using american $$ to invest offshore only works for the corporate sector) to smooth out the ripples further.
I'd call all the loans (IOU's) within the next 24 months and DCA the balance over that time. New excess funds would be used to buy government paper if it was needed within the next 5 years, otherwise allocated.
Back of the envelope calculations push the "reckoning day" close to 2100. Odds are there will be some global calamity by then that will save the grab and spenders from fulfilling their promises.
