the reason the pay is so low is that it’s part of a PhD, usually, so the TAs tolerate it. i don’t think you could hire someone to just be a TA full time at those wages.
you can’t admit more PhD students, necessarily, because to graduate they need to do research under an advisor, and access to grants/projects won’t necessarily grow along with required teaching staff.
