My daughter-in-law the vet tech is not happy with the financial rewards of what she's doing, although she very much enjoys the work. However, she indicated that if a tech can get certified in something like anesthesia, radiology, intensive care, or physical therapy, and can find a job in a larger animal hospital (read, larger city) then the money is more adequate for keeping one in clothes and shelter. Oneself, not the animals :). She also indicated that large animal training -- especially as regards horses -- is an elite field. Massage therapy for horses for example.
Best of luck,
