I feel that you're driving "we're just gluing libraries" argument to the point of absurd. Do you think that designing database schema and queries that run over it is something that is extremely rare and high-level in modern web development?
It's not rare, yet I find myself redoing this over and over with every job. Web apps that are a HTML table fronting a CRUD back-end and simple database schema are all too common.
I hear you saying "well, that's your fault you keep working at those companies" - and that's not too far from the truth.
