Most common training of CCP membership: Engineering
Face it, we are a litigious nation that values due process (with one exception of course) over making things. An influential idea or book isn't changing this, it's in our DNA somehow
Societies require vision of a future, something engineers are apt at creating. Empires require labyrinths of laws to entrench power, which lawyers excel at litigating. A thriving country requires both to be balanced, such that its benefits are distributed to all.
Your premises are so wrong that it is hard to argue with your conclusion. Ofc politicians, or policemen, or lawyers, train in law more than engineering. The US is more litigious than many countries because... it works better to litigate there, maybe ?
And to further make the point, the US has been the center of innovation for decades. There’s a reason Silicon Valley is in the US. Other countries are catching up, but wasn’t that always to be expected?
