I think you're suffering a bit from sunk cost fallacy and a little bit of "got mine", there's absolutely no reason to continue this.
I (and practically all of my friends) may be outliers, but if nothing else it's proof that you can do highly specialised jobs with vocational education.
As mentioned, higher education has massive value to society, but if it is product that forces you into a considerably unfavourable economic position from the beginning of your career, and certainly not as a gate for establishing yourself to employers -- that it has been used that way does not mean that it's a good idea.
There are many stupid things we do as a society, like changing our clocks backwards and forwards every year; the only reason it continues is inertia and our stubbornness to change.
