> Truly a Godsend in my opinion.
Perhaps you are using "Godsend" rhetorically, but it was hotly debated and even opposed by members of Congress who felt that the class of people who physically fought the war had no place in institutions of higher education [1].
Some members of congress opposed it on the grounds that it could in theory help African Americans:
"On March 24, the Senate passed the G.I. Bill unanimously, but the House continued to debate the unemployment and education provisions for another two months. Rankin, chair of the House veterans committee, had evolved into one of its sharpest critics. An unrepentant segregationist, he worried that African-American veterans would use the benefits to avoid work and live off the government. Rankin also didn’t see the need to give African Americans the same benefits as whites." [2]
In the end, ways were found to exclude African Americans from the benefit even after the bill passed [3]. The generational knock-on effects of that are well documented.
But the tremendous value added to the economy because of government support (however unequal) of regular "non-genius" people is pretty well demonstrated by the successes of the GI Bill.
