Maybe you're an autodidact like many other engineers, and maybe you would have done better without schooling. Such people are a minority.
Like many, I think you're confusing "the school system is flawed" (it is) with "school bad."
If the schools in a given country were pumping out geniuses year after year then maybe you would have a point.
The unintended consequence of this is all the junk mail that makes regular mail a horrible experience to interact with.
