In our great grandparents' time, a high school education was considered enough, but those days are over. These days, a college degree is a goal that an increasing number of people are pursuing. The job market is more advanced and competitive than ever. An individual with job skills has the best chance of landing the most desired position. College graduates are also less likely to be unemployed than those with less education. The need for college-educated employees is also expected to remain high. In 2006, the US Bureau of Labor Statistics predicted that between the years 2004 and 2014, 55 million jobs will be filled by college-educated workers. The Bureau of Labor Statistics also predicts that positions for college-educated workers will increase at a faster pace than positions for non- college graduates. According to the US Census Bureau, an individual with a college degree can expect to earn an average of $2.1 million throughout his working life, while people with only a high school education can earn $1.2 million. This important difference in earning potential is predicted to widen, as more jobs require some college education. People with a master's degree can predict to earn $2.5 million throughout their lifetime, while those with a doctor's degree can foresee earning $3.4 million. There is also evidence that proves that education benefits the brain's physical health. Studies have showed that highly educated people are less likely to develop various forms of disease. For several older adults, returning to college for fun has brought joy to their golden years.
