Students, the media and the general public have shown much concern over the value of getting a higher degree in the US ever since the Great Recession of 2007. A 2015 survey of 2,000 adults (900 of which were graduates), implemented by an education technology company called Greenwood Hall, reported that more than half of the graduates surveyed believe those getting their degree now will be receiving a lower return on their investment than their counterparts 10–15 years ago. Media coverage of the rising costs of higher education and increased student debt have also affected the public's perceptions of whether higher degrees are still worthwhile. Statistics citing that college graduates make around $1 million more in their lifetimes than those who didn't attend college and living longer, healthier lives work in favor of those who argue the continued value of higher degrees. Studies like the 2011 Learning Gains study by Arum and Roksa, on the other hand, reported that only 55% of students had any learning gains during their first two years of college, which favors the argument that investing in higher education may not still be worth it. As academics continue researching and dissecting these arguments, education remains a hot topic in the US as shown by President Obama recently setting a national goal for the US to once again have the highest proportion of college graduates in the world by 2020.
