My overview of American government goes generally like this: (1) Something happens. (2) The government passes some laws in response to it, adds on a few pork projects, and raises taxes to pay for the laws and the pork. (3) The laws (or pork) cause an entirely new problem. (4) Repeat.
The usual outcome of this cycle is that every year we have more laws and higher taxes. But every so often, some accidental side effect occurs and something awesomely good happens. So it was during the alphabet-soup days of New Deal government during the Great Depression. The accidental side effect was the Golden Age of American Photography. How it happened is rather interesting.
