It feels like the difference between today and projects like the hoover dam is a combination of: * Private sector grift/contract savviness * Government corruption or lack of authority to deal with above * Individual safety prioritized over all else - work stoppages for the most relatively minor of unsafe situations * Environmental reviews/lawsuits * Cost of modern materials/manpower * Lack of will over the past 30 years to fund necessary maintenance As a total layperson who doesn't work in either construction or government, I'd love to hear whether I'm on the right track here.
