I don't agree with the normative implication here, but strongly suggest you subscribe to the Wall Street Journal. It will help expand your worldview vis-a-vis questions like "Is accounting Important?" or "Is $41 million a lot of money?"
Did the person you're responding to somehow say accounting was not important? How will the Wall Street Journal help me understand that further and why do you assume we need that insight based on all of this?
Could we stop arbitrarily dismissing things that are important to hundreds of millions of people as "silly"?
Anyway, you're free to disagree with this thinking. I disagree with many instances of it. I'm just explaining why the software industry is different.
Relative cost structures are really complex; a mind-numbing TV show that people use (instead of alcohol) to cope with their jobs may save more lives than an exceptional charity.
If we think something is retarded and yet millions of people do it, we either have different values than them or have failed to see the value. Neither puts us in good stead to judge those people.
Unless we actually prefer a world of Moral One-upmanship ....
I became depressed the day when realized that some of most bright engineers working for one of the most unique companies of our times spent their time and energy and intellectual resources on cloning a social network (google+ vs. FB). And I'm not really claiming that they should save the world or anything, I'm just saying that with the huge amount of data that they have gathered so far and considering the human capital they have available they could start answering a lot of very interesting questions, which gave bugged us as an intelligent species for quite a long time (think linguistics-related issues, for example).
Other proudly shallow businesses are probably acting and music, and many actors and musicians actually like to point to their side projects of saving the world. I guess it helps them feel more confident with what they spend their life on too.
The way I see it, we are the only generation that has had access to the computing power and knowledge that we have. It's our responsibility to take advantage of it since many of our ancestors dreamed of such things.
