The modern welfare state (post-1930) did create a huge number of these stunted people. UBI will create many more, and it'll be a generational compounding effect, as the stunting increases through generations and we develop familities where no ancestor has worked for 3+ generations.
Just reflect for a moment on how many of such stunted people existed in 1925, compared to today. Now apply that difference again a few more times, to a segment of the population with above-average fertility, and guess how many generations such a system can last.
If there were no stunted people, why did the welfare state get created? And do you have any evidence of this increase, or did it just codify the problem that already existed?
