Give Me the Money! Four Sources for Faculty Salary Increases

Like many institutions of higher learning, the past five years have not been kind to faculty salaries.  For example, a recent AAUP study states:

An annual survey of faculty salaries being released today by the American Association of University Professors paints a dismal picture, suggesting that a historic low period for compensation increases continues.

At our public institution, the president of the faculty senate stated that that there are four sources for increasing faculty salaries:

1. increased state funding (direct appropriations)
2. increased private giving
3. increased tuition and student fees
4. re-slice the pie of the current resources

This seems like a complete list to me.   What are your thoughts?   Where should the funding for increased faculty salaries originate?
