I couldn't agree with you more that nursing is a tough job that deserves excellent pay (though out here in SF, registered nurses do earn more, at the median, than software application developers, though this is a bit unusual and not the case in most areas). It would take a tremendous amount of time, training, and effort to turn a software developer into a registered nurse, no doubt.
I am pretty bummed to hear a developer speak so dismissively of what it takes to be developer. I'm not sure what you mean about an "entry level" web job, of course - if "entry level" entails no background or skills, then I suppose I could prepare someone in no time at all.
However - and I fully acknowledge this is just anecdote - after 15+ years in the field, I have yet to see the mythical simple CRUD app. I came into this field after a major in math with a CS emphasis and a MS in Industrial Engineering, during which I wrote a lot of code for various numerical analysis problems. I've written apps that need to build and solve linear programs with a few million variables and communicate results to analysis within one minute, which we felt was the maximum amount of time anyone would wait for an interactive tool designed to explore multiple supply chain scenarios. It is hardly a work of genius, but these were real CS and math problems, with a dose of programming optimization.
In many ways, those projects were considerably easier than the "CRUD" projects I've been on. Seriously. You have to gather business requirements from people who do understand their business, but aren't accustomed to explaining it in a way that works within the strict confines of computer code. You often have to work with existing code bases, deciding how much customization you can get away with before forking yourself into a maintenance hell (and you have to deal with that maintenance hell). You have to integrate with many different data sources, back and forth, over networks, many of which are obscure, poorly documented, and poorly maintained. You are pressured to provide estimates and deadlines for systems that you have no idea about (how long will it take me to alter a code base for an existing application to integrate with a data source that I haven't studied yet? Uh, a week?). You have to weave through existing data structures, code bases that involve intricate logic, uncover magic documents that nobody told you about, interview and talk to business analysts, test, design UIs or work with UI people... and often encounter an (at best) irritated look when you didn't meet your "estimates" that turned into deadlines.
I maintain that even the "simple CRUD" projects are difficult, stressful, and require a very high level of logic, coding ability, and the ability to communicate will with people at many levels of an organization.
If you truly believe that web dev is simple, of course you have every right to make that point. You shouldn't back of from saying what you think is the truth just because the truth is harmful to the reputation of developers.
What pains me is that I absolutely don't agree with you, I think it's a really hard job, and I think we developers really hurt ourselves when we trivialize our jobs this way.
