It's funny but I took a project management course once and instead of Man hour I used "person hour".
A heckler asked me, "what's a person hour?" My response was, "about two man hours".
He shut up.
As to your question, I believe that emphasing labor costs over performance leads to software that is bloated and it's not the best we can do. Yes, I'm an engineer and I'm also an artist. Over the years, I think your design philosophy leads to software that dimishes hardware performance gains. I used to write drivers in VMS engineering. Never once did I see management worry on a local level worry about the cost to write a piece of code. I remember my last project. in the early nineties. My one year, one woman project returned 105 million dollars in revenue. That's quite an ROI.
The emphasis was always on performance and elegance.
Please excuse the poetic license.
