Now we must develop progress, or rather, a program—and I can’t stay on this long—that will drive the nation to a guaranteed annual income. Now, early in the century this proposal would have been greeted with ridicule and denunciation as destructive of initiative and responsibility. At that time economic status was considered the measure of the individual’s abilities and talents. And in the thinking of that day, the absence of worldly goods indicated a want of industrious habits and moral fiber. We’ve come a long way in our understanding of human motivation and of the blind operation of our economic system. Now we realize that dislocations in the market operation of our economy and the prevalence of discrimination thrust people into idleness and bind them in constant or frequent unemployment against their will. The poor are less often dismissed, I hope, from our conscience today by being branded as inferior and incompetent. We also know that no matter how dynamically the economy develops and expands, it does not eliminate all poverty.
