-Being a truck driver: you're moving boxes around
-Being a professional hockey player: you and your team are moving really fast with a disk shaped object trying to put it in a net while people try to prevent you from doing it
-Being a stock trader: making money by spending your whole life reading company reports and hoping you're right about whether they're doing well or not
-Being a quant: using your hard earned computer science skills to move money around and turn a profit instead of helping humanity
Almost every human endeavor can be trivialized if you choose to only see one side of it.
You're right in some sense, although I think those other fields are different in that people are honest upfront about what you're doing, and people see the value in the tediousness.
Academics, though, reached some inflection point (not too long ago really) where papers are just published, or grants proposals are written, just so it can be put on a CV. There's a huge discrepancy between the activity and its purpose, and a lot of denial about what's going on.
The denial seems to be decreasing a little, with more and more pieces like this Nature article, but I don't think the general public really understands the nature of the problems involved, nor are scientists really often honest about the nature of scientific work today.
One issue that's missing from this article is the impact of these trends on senior academics: it makes it almost impossible to move from one institution to a next, because of the volumes of young Ph.D. grads that are available. So if you are stuck in a problem institution, or in a poor institution-fit, or your spouse needs a job elsewhere, you're f*d, to put it mildly. This then creates all sorts of problems up the chain, where you have senior people whose careers would improve if they could move, and people staying would be happier, but they can't, or it takes forever. It leads to all kinds of problematic interpersonal problems that would be resolved easily in another field by someone just moving someplace else they'd be happier at. In academics, your career is often tied to a particular institution, because of the glut of qualified graduates, which is totally screwed up.
Academics has become cannabilistic. You're expected to just sort of throw yourself and your family at the altar of "science," the meaning of which is increasingly corrupted and distorted.
Farmer: you're making food for people.
Construction worker: you're making buildings for people to live or work or play in.
I think the problem is that many of our jobs are crappy, not that almost every human endeavor is equivalent to pushing paper around. Nurses, doctors, etc, are doing important work as well. The bad part is when it's 90% paper (common in healthcare in the US).
Find you a tech company that is actually building something physical, not just selling ads.
As far as being well-paid: farmers are fairly well-paid. They have to work hard and use a LOT of what you might call automation (combine harvesters and the like).
But to your point: I sometimes am persuaded by the conjecture that we developed BS paper-pushing jobs for people since we've automated away farming, much of manufacturing, etc. Office Space comes to mind, too.
As for the ethanol, it's a fuel, but without the subsidies and legal mandates would there be a good reason to use it? I'd always heard it's not really efficient and the environmental impact is negligible-to-negative, even though on the surface being renewable is good.
But I digress.
Currently departments are pressing researchers towards output rather than long-term quality work - at least that was the key aspect of my post-doctoral experience.
Some of the horror stories I've heard from older people who have done a PhD are awful. For example, apparently, it's quite often that there will be a collection of people gossiping when a particular upper senior will retire or die so that they can all compete for the opened slot. It's quite terrible and grimy when you get past the good PR angle that the Universities and mass media portray. Just like any bureaucracy.
There are many downsides to academia, the papermill mentality that has become pervasive being a big one, but this picture of a morally bankrupt subculture where people do whatever they can to get to the top is nothing like what I experienced.
Something must have change in recent years, which changed the way scientists work nowadays. While I left academia too, I wish scientists would have the freedom to work on larger/long term subjects again.
Then you have to write other documents (grant proposals) to grab money to write more documents (papers) by gaming the inner mechanics of some comittee.
If partner-track investment bankers are overworked, depressed sociopaths with Lamborghinis, then tenure-track postdocs are investment bankers with crappy bicycles.
Needless to say, I left academia 3 years ago and never looked back.
