ProfondoRosso practitioners in my profession do not tend to do pHDs because they are too busy practising their profession. In fact, a PhD would be considered a negative unless the student were making an academic career, because it would imply that they lacked the ability to practice. This is relatively standard in the traditional professions.
As a taxpayer, voter and person with common sense, I feel perfectly entitled to state that a PhD on the History of the Labour Party in Scotland taking 10 years to complete is a waste of time, except to further personal political ambitions. I don't think its something that the State should support or finance. Its not as if it even resulted in a well regarded textbook.
As I said previously, if he really was interested enough in the history of the Labour Party in Scotland to spend 10 years studying it at the expense of the taxpayer, I am sure he could also have produced a leading text or two on the subject, whilst holding down a paying job.
Furthermore, the former PM's career is in the public domain I do also feel justified in stating that Gordon Brown's employment record, prior to entering politics, was limited and unimpressive. Funnily enough, it is heavily glossed over in most bios of him.
What would impress me is a good degree from a good university in a good subject (not necessarily a professional subject but the preponderance of Arts subjects isn't a good representation), a good further degree with stints abroad at least, on the Erasmus programme if the student for some reason is unable to bring themselves to pay the cheaper fees in our neighbouring European countries, a good employment record at a reasonably high level, progressing from junior employee to that level without benefitting from familial connections, and/or a history of running their own business. Additional achievements in sport (like Menzies Campbell, Seb Coe), or all rounded interesting personality are a bonus.
Is that clear? Gordon Brown doesn't really meet the requirements I see that would make a good PM, and its borne out in his rather dismal record in office.
