The industrial motor setting was most relevant to Ayn Rand's time and fit the book well. I could see the same meeting of the Federal Reserve where a young financer by the name of Satoshi stands up and walks out to stop the modern day motor of the US, the financial sector.
Except that the financial sector isn't the motor of the economy, but is rather a bloated parasite sucking the life from it.

But your referral to "the financial sector" (hey that's us) is not exactly what you meant to say.
No Atlas, credit creation fraud and counterfeiting are not motors of industrialization.
