Use your extensive medical background you have obtained through your MT/MLT education to put towards another medical career that is better paid and in more demand. Have you looked into an extended career in Physicians Assistant, Nurse Practitioner, LIS, Sales, Technical Representitive ? You could also further in to a MD or PhD in a science. An MSEd in high school science education could be both interesting and challenging.
Unfortuntately the MS / MBA in management in a laboratory environment is not in great demand and you could be in a long line awaiting a position in this area.
