Over what time frame? A year? Sure. But three years? Five? Ten? It's simply not sustainable for 95% of people. And it's unrealistic to hold everyone else to the standard of that 5% who are 1) naturally hyper-productive or 2) have little else going on in their lives.
The cynic in me wonders if the attempt to turn overwork into a virtue is just to keep people busy enough that they don't stop to wonder what it's all for in the end. Somehow everyone seems to have forgotten that the economy should exist to serve people, not people serving the economy.
