"Predicting is hard, especially the future." Nevertheless it was a popular pastime in the early part of the 20th century. Needless to say, 1945 probably looked nothing like that envisioned or hoped for by some members of the class of 1930. By 1945 they had gone through the Great Depression, a major war, and would then enter another economic setback as the country tried to get back to a civilian economy. Only to then see the Koren "conflict" begin. So for something like 25 years after the class of 1930 graduated the world was a very turbulent place.
