Estimate the gap between those who hold bachelor's and higher (master or doctoral) degrees and those who do not. Explain reasons why the inequality gap between educated and less-educated workers has been widening. Evaluate whether increasing opportunities for higher education can reduce income inequality. Analyze what else causes U.S. income inequality to widen. Recommend how to reduce educationally based income inequality or other factors if you were a federal policy maker
