Obviously that's your opinion, but since when does the effort it takes to create something matter about the price? It's pretty trivial to move product from a factory to a retail store, yet people have no problem paying for that.
And again, if it's trivial, then there is nothing stopping anyone from starting their own journal. But amazingly, nobody has done that.
What's the saying about "find out why the fence is there before you tear it down"?
Most journals are not "high quality.
Who cares about most journals? Nobody reads them anyways. I'm talking Nature, Science, etc.
