Lack of Ph.D.'s a Real Problem for RT

I can't stop worrying about the lack of universities with Ph.D. programs in RT. As far as I can tell, there are only four universities today that produce Ph.D.'s. Our profession faces a crisis in that faculty are retiring and there are so few scholars with Ph.D. degrees to replace them. Every profession needs Ph.D. trained scholars to provide research and scholarship for the profession -- so the lack of Ph.D.'s should be a concern for all in our profession.
