Nearly four stars but deducted due to the fact it's a bit on the dry, academic side and is both exhausting AND exhaustively researched at the same time. Pretty interesting topic of Henry Ford's attempt to build a jungle city in Brazil that would produce rubber for his empire in the late 1920s and throughout the 1930s. He spent millions on the project, hundreds of people died and the rubber farm never took off as it was intended too, but a city in the jungles of Brazil was built with paved roads, power, running water, houses, stores, a golf course and other things that make a city.
All kinds of topics in this that I like reading about--industrialization, unions, manufacturing, survival in the wilds of a jungle, the great depression. I just wish the writing would have been a little zippier, but it's just so dense a story that it felt like work at times. Still well worth the time and effort though if you like any of these kinds of subjects.
