Because you have, in 90 (99?) percent of instances a smart person (probably IQ 120+) doing a stupid menial job that requires a level of competence that only someone smart can provide. So to prevent themselves from ending it all, they invent things to do to keep themselves sane while they churn out CRUD apps all day long for decades. Sometimes you get truly amazing software, but most of the times it's just reinventing the wheel, but worse. Even worse, some of them become infatuated with doing things "Like Google," and errant CTOs enable them, leading to a 6 person team supporting a piece of software that could be replaced with WordPress, to the betterment of the primary stakeholder. I've been consulting for over a decade now. The number of times a potential client has told me they've spent into the six figures (or eight) for something that free software does out of the box but better is depressing. The worst part? I usually can't convince that person they've been absolutely swindled, and so I have to let them keep on their merry way.
