Fact is: helping adjuncts implicates the system (if they didn't need help, then no one would be helping them...).
Fact is: tenured profs (on the whole) do not care to disrupt the system that employs them--this means you "Larry"--else the system would be changing (tenured have the power to change the system but are not)
Fact is: adjuncts did not choose their fate. They didn’t one day wake up and say “I think I will accept sub-standard wages without benefits or security. I mean, after all, I would love to put my advanced degree to work for a system that subjugates me. Ooh, that sounds like fun.”
Fact is: large PhD classes lead to a disproportionate supply of cheap adjunct labor (the university system as a whole makes money on the advanced degrees and then on the adjunctification of that same degree)
Fact is: no one in power cares about the above facts.
