The premise that 80 hour work weeks are somehow more productive than 40 hour work weeks is known to be false in the typical case. It's not the hours which determine your productivity, it's the engagement and motivation. Most people who do 80 hour work weeks slack off during a majority of that time and probably realize lower productivity than if they had stuck to a 40 hour work week.
Making your workforce do 80 hours instead of 40 does not make them more productive. Motivating workers and putting them in control of their own work is what gets stuff done.
