So, the Union of Concerned Scientists, or one of its members, finds economic justification for politicians subsidizing their pet projects by extracting resources (subsidies = taxpayer money) from those who literally stand to lose should they miscalculate---who know their investors will look elsewhere should their enterprises not yield substantial profits (as opposed to substantial political gains)---oh my!
Comparing simply the survival rate of venture capital-funded firms with government subsidized firms is like comparing two groups of organisms: one existing in nature, left to brave the elements (thus, the survivors growing stronger with each successive challenge to their existence), to a group that exists in a lab receiving a steady flow of synthetic nutrients. No doubt, over time, the mortality rate would be higher for the organisms exposed to the elements. But imagine what would happen should the lab-raised organisms be released into nature. No doubt the study would abruptly turn on its head.
