> I believe it's essentially impossible to perform truly novel academic research when your personal finances are volatile.

Your belief is well-founded: the effects of stress on performance are well-established, and financial instability is one of the major stressors.

> I also firmly believe that graduate student unionization is an elitist mentality that must be unilaterally opposed

...and you've lost me. Student unions are trying to achieve stability for those who are not independently wealthy. Calling it elitism doesn't sit right with me. Absent improved income for the working students who need it, the suggestion that only students from wealthy families should be the ones exclusively pursuing PhDs is the real elitism.
