> will require more 60-70 hour work weeks to pay back. Except if 60-70 hour workweeks created the debt in the first place, subsequent ones can be expected to create even more, rather than (net) paying any back. Perhaps a better remedy would be 1.5x-1.75x as many 40 hour workweeks. If so, that could easily be more years than the average engineer's tenure, which can add its own challenge.
