Jesus does not say parables "are quite communicative for the general audience."
On the contrary, He tells us he is speaking in parables for the express purpose that only those with ears to hear will understand them.
Maybe you didn't read the verses by Jesus that I posted. Maybe reading them will help clarify this for you.
I read them. But not with Calvin’s decoder ring I guess.

To put it another way: The Prodigal Son is not Jabberwocky.
