Following World War II, one of the best examples of a successful government program was the G.I. Bill. Once passed, thousands of service members returning from war were able to get an education, earn their degrees, start a career and make a great deal more than they would have otherwise. The overall economy benefited from the influx of workers able to earn higher wages and the country, as a whole, benefited not just from the increased economic activity, but from the overall improvement that came with it. The gains for society were exponential.
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.
