I think this is an orthogonal point. Certainly there are lots of bad developers in the industry whose code appears to only work by accident. But there are just as many of them doing greenfield projects as maintenance tasks. In fact, I would guess that in growth-oriented companies there are far more of these bad developers doing greenfield projects.

The issue is that in many companies there is constant pressure from management to "innovate" by building new features or new products, even if they are of no particular utility. New stuff will bring new customers (or new subscriptions from old customers) and that will either make you personally rich, or at least look good on your CV so you can leverage the experience into the next job where you can get rich. And if the project fails, it still leaves you looking more valuable to the top brass than the people who quietly kept the systems running, because you took risks and had big ideas and showed a growth mindset.

I didn't really notice this at the start of my career, but once you see the pattern it makes so many jobs incredibly depressing. People just keep building more and more crap to advance their careers and enrich the shareholders, even when very little of it is actually useful. It's even more depressing in B2C where it becomes apparent that a large part of the money comes from exploiting individuals who simply get a buzz from buying new stuff, no matter what that stuff does or how good it is.

Personally, I am much more happy to work on an established system that already has real customers that value what it does. The phase of throwing huge amounts of crap at the wall to see what sticks is over, so what remains is an actually-useful piece of software that's full of bugs and superfluous functionality that the "innovators" (comprised of both good and bad developers) left behind. I think it's worth it to have good engineers dedicated to this role of taking the mess and refining it into the best version of the thing that customers actually want. Leaving that task to the bad developers will just result in the system eventually collapsing, which might not matter to the entrepreneurial types who only care about growth, but it does matter to the customers who were getting value from it.
