I must side with J. Berkley who sides with M.  There are many simple
methods of saying complex things: E=mc2 is about as simple as it gets--
but woe betide the one who tries to explain it without jargon....
Jargon in and of itself is value free; it is, as was pointed out,
a shorthand by which one signifies larger and more complex concepts and
constructs.
Jargon used to make others feel less than what they are is snobbery;
jargon used to identify and summarize relatively non-controversial,
agreed-upon conventions concerning given phenomena is economical,
plain _and_ simple.
