It used to be one of the best paying professions, so there is plenty of people who aren't meant to be software developers, but they tried to get money and now suck at it.
Now that standard of living increased by a lot there are other specialists that do not require this much education or talent (but still you need to be decent) and pay comparably or even more, because there is just so much demand for them if they are high quality (people wait for months). Those are mostly people who build, finish or otherwise improve houses and cars. Even unqualified labor got decent pay now, tho still about 1/3 of what average dev will make.
