EARNINGS BY DEGREE Average annual earnings by education: Final degree earned No asso-ciate degree With asso-ciate degree Bachelor's $54,667 $52,022 Master's 61,323 56,997 Doctorate 71,246 62,906 Professional 79,491 70,349 Source: The Federal Bank of St. Louis, based on data from the 2003 National Survey of College Graduates

Most workers who have a degree from a community college can earn more than a person who had no formal training after high school. And even if they never complete a two-year degree, students who attend some community college can get higher-paying jobs.

But what if that student goes on to earn a bachelor's? A study being released today shows that people with a bachelor's degree who transferred from a community college earn less than those who start at a four-year school.

The pattern continues even for community college students who go on to earn a doctorate or a professional degree. And it holds for people of the same gender, race, education, experience level, field of study and type of college attended.

Natalia Kolesnikova, an economist with the Federal Reserve Bank of St. Louis, calculated the data based on the 2003 National Survey of College Graduates, a joint project of the U.S. Census Bureau and the National Science Foundation. Her findings support previous studies suggesting a "community college penalty" for students attending Ohio public universities.

She says more research is needed to understand why that is. But she adds: "It is important for individuals to know both the benefits and the disadvantages of attending a community college when making decisions about education."

您看完之後，會不會跟我一樣覺得這個新聞很好笑？
這些記者不知是太笨還是太壞！

唸二年制 community college 是結果，不是原因。
不是因為唸了 community college 之後，薪水變少了；而是因為（各種原因）受教機會或是聰明才智比較差的人，只好先去唸 community college。所以當然也影響了他日後的收入！
要這樣推論才有羅輯麻！
