7, 23, 24 were driven by the common unusual political occurrence of fair economic opportunity. These rare times where a balance of power occurs, by special circumstances, between the former autocratic rulers and everyone else.
In Britain (7), domestic Royal monopolies were abolished etc creating an economic and legal environment where entrepreneurs would be rewarded. So people started investing their very expensive free time tinkering because it might lead to profit.
Ancient Greece (23) developed the Solonian Constitution which similarly protected the property rights of ‘citizens’ like never before, so Athens became a cultural center of tinkerers, hustlers, thought leaders, influencers etc, and the ideas are what we still have today. Because unlike with Ancient Phoenicia, the Greeks wrote on clay, not on perishable papyrus.
(24) Obviously the US Constitution managed to establish unusual property rights for its European male citizens, and again we see hustlers, thought leaders, influencers etc, because their efforts are far more likely to be rewarded. But this time we see what this political environment looks like close up and we see regular people’s bright ideas materialize in society because the law protects them.
I am thankful that we still today, I mean 11/26/2021 today, still maintain the balance of power that enables our egalitarian laws to stand, and hope that some new technology won’t kill that balance.
