“would imply in a 20% increase in valuation for the working hour.”
I’m nit-picking but the increase would be 25% not 20%.
For example:
You work 50 hours per week for $100 at $2 per hour. A 40 hour work week at $100 would be $2.5 per hour.
$2.5 is a 25% increase over $2.





So effectively a ~1GW plant if my maths is correct.
