There's a third, and I think more common group: folks who know all that's involved with reinventing the wheel, and how to do it, and know the juice of doing it isn't worth the squeeze, and there's no value in doing it yourself, educational or otherwise.
I think this view of things is usually related to the fact that large parts of this group are simply too bad at reinventing wheels and in large part are gun-shy because of previously failed attempts at doing a good job.
One of my former leads had worked for 7+ years in the same company by the time I showed up and he was absolutely useless as a programmer beyond just gluing together libraries because that's all he had ever done. He barely also knew the platform we ran on because he simply had developed no skill when it came to understanding things.
For him and people like him reinventing wheels is simply not worth the time and since they're so bad at it and always fail they'll never actually learn anything. I heard from him last year (7 years after we both left the company we worked together at) and he still only glues libraries together, but he does it in Rust instead of Erlang nowadays.
