I think a difference of purpose is to be mentioned here. Not all people are the same, some strive for different aspects of life than others. Using your example, some seek family, a close social circle, a white-picket-fence life. There's nothing wrong with that, but another group seeks relative solitude, doesn't see a purpose in creating a family or having a nice house, and fills some kind of intellectual hole, be it with creative writing, or relatively non-conformist research. My point is, I don't see Bukowski as one who lacks empathy, rather, someone who follows his own purpose, though, potentially blind to some others' happiness doing other things. Lastly, the workforce ethics back then were quite different from today's. It's my understanding that the pay was significantly lower compared to costs of living while progressing in ranks was near impossible without a degree.
