I get what you're saying. Though more is not necessarily better, I have no doubt that someone with abilities similar to myself without a family could put in more effective hours and outperform me.

Like so many things in engineering, I have analyzed the situation and made the tradeoffs that i think provide the best solution to my particular situation.

That's exactly what I meant. The responses to my comment I mostly agree with. Diminshing returns are true, but businesses pay attention to total output, not per-hour output. To say a childless workaholic with no interruptions will somehow accomplish less in 80hours than a family man will in 40hours is just not accurate. If you were a woman complaining about a pay gap, people wouldn't hesitate to point this out.

It is a sacrifice, but I consider it the right one. That the choice costs something only shows how seriously we take it. I'm just trying to add some perspective for those with an odd definition of "fairness".
