According to Education Dive, "Inequality.org predicts that income inequality could move onto the 'public policy center stage' in 2014, referencing proposals in Switzerland, Germany, France, Spain, and the U.S. to tie chief executives' compensation to that of their workers, usually via ratios."

Income inequality is often discussed as a gender issue, but as students struggle with loan debt, it's becoming a hot topic in the conversation about education.

The Chronicle of Higher Education compiled figures for private college presidents' compensation packages in 2011 - the most recent year available. The top 15 packages ranged from $3.36 million to $1.36 million, and included three Ivy League Universities and three female presidents.

Twelve of the top 15 schools are in the Northeast. The exceptions are the University of Chicago, which comes in at #1, Florida Institute of Technology (#7) and University of Southern California (#13).

Expanding to the top 25 still shows an overwhelming majority of schools in the Northeast. The only other schools in different parts of the country are Northwestern University in Illinois (#16), Wake Forest University in North Carolina (#19), Kenyon College in Ohio (#20), University of Miami in Florida (#23) and Vanderbilt University in Tennessee (#25).

To get the data, The Chronicle of Higher Education compared the compensation received by 550 chief executives at 500 private nonprofit colleges during the 2011 calendar year. According to the Chronicle, numbers were compiled from the Internal Revenue Service’s Form 990, which is filed by most nonprofit entities.

"For our analysis, we selected the private nonprofit baccalaureate, master’s, and doctoral institutions with the 500 largest endowments, as reported to the U.S Department of Education’s Integrated Postsecondary Education Data System, or Ipeds. Some nonprofit universities don’t report the value of their endowments to Ipeds, and those were excluded from our analysis." - Chronicle of Higher Education
