NURSING AND EDUCATION PLATFORM

What purpose do Degrees really serve? Today one can obtain a Deree in almost anything eg study a specific celebrity. Yes it enables one to be more aware of research and hopefully to think more. However what purpose does pure theory serve? Degrees need to be practically linked. For example in nursing, one can learn theory but how can it be applied in practice? There are many dilemmas to consider-- what if the client refuses the medication or food or care offered? What if there is insufficient staff to enable these wonderful policies and theories to be met? What if one is working in other countries with different resources or care homes compared to NHS? The same no doubt can be said of other fields- psychology or joinery or education. We need really to consider how to apply theory to practice and overcome and restrictions.  Also, why do Degrees at all? Are they a political tool? I know some excellant thinkers who do not have  a Degree.
