Bachelor's degree
Until the 19th century, a bachelor's degree represented the first degree in a particular faculty, with Arts representing undergraduate study, thus the Bachelor of Civil Law (BCL) at Oxford and the Bachelor of Laws (LLB) at Cambridge, for example, were postgraduate degrees. Vestiges of this system still remain in the ancient universities, with Oxford and Cambridge awarding BAs for undergraduate degrees in both arts and sciences (although both award undergraduate BTh degrees through associated theological colleges, and Oxford awards BFA degrees in addition to the BA) and defining other bachelor's degrees (e.g. BPhil, BCL) as postgraduate awards equivalent to master's degrees, although many postgraduate bachelor's degrees have now been replaced by equivalent master's degrees (e.g. LLM for the LLB at Cambridge and MSc for the BSc at Oxford). The same historical usage of indicating an undergraduate degree by it being in the faculty of arts rather than being a bachelor's degree gives rise to the Oxbridge MA and the Scottish MA).
Academic capital
Whereas the biggest stepping stone to attain a higher paying career used to be an undergraduate degree, the common discussion in today’s market is the devalued status of a Bachelor’s degree. A Bachelor’s degree no longer holds the same academic capital it used to, and holding such a degree no longer entitles one to the same job opportunities and income possibilities it used to. Government statistics reveal that over the past 8 years, the average weekly earnings of individuals with bachelor's degrees have actually decreased, in relation to inflation, by nearly 2%. Therefore, many individuals are studying beyond four-year institutions in order to increase their capital and ultimately their income. When compared to an individual with a bachelor's degree, an individual with a graduate degree makes, on average, nearly $75,000 more annually.
