I cannot think of a single industry where such a drastic increase in the licensing fee required for the license to work is considered as a plausible option. New graduate nurses are already coming in to the profession with mounting debt, and will have to find a way to pay an even higher initial licensing fee. Renewals are increased, and these fall within the first years of establishing a career. These newest nurses have barely begun to pay their student debt, build a savings account, or start retirement funds. They are living on an hourly wage that is already much lower than the promised base increases and wages of nurses in states around Virginia. 
This deficit is one from a change made 8 years ago. Logically, the expectation should be that a revenue loss would take at least 8 years if not longer to recover. A sustainable increase, continued market analysis of pay rates, and legislation to ensure positive changes in nursing practice should be the primary focus.
