thats why I said most degrees
Way back when, it was like a "reward" for those who maintained a certain academic standard (like you said, *some* jobs wont consider you due to the academic standard associated with the degree like law or some companies place/expect a high standard on/of their (potential employees-as per your desire/wish job).
As I said, in most degrees, it is a waste (for want of a better term) as the potential job doesnt warrant it (eg arts, nursing, psychology-did I spell that right??doesnt look right-education, welfare, in general, most humanities strands) as the job will entail further/ongoing training as a part of the job. + a masters is more recognisable in most jobs (its extra letters after all!) as it shows further study after your undergrad (as opposed to apart of your undergrad.eg in education its desirable (almost compulsory) for academic/educational leadership positions as it shows desire to extend skills ect. Hons doesnt do this as its done as apart of your undergrad)
Granted, hons does have a place in some areas but thats only because of demand and assumed prestige (IMO) therefore its a "false" assumption to force students into further study.
My masters attracted HECS so I cant comment on your HECS comment. Yes, you can defer HECS on your hons but thats because its apart of your undergrad!
Ease of getting into masters again I cant comment as post grad work in the humanities is basicly open to anyone who wants to do (and can pay!). Havent heard of anyone skipping a msters straight into a phd based on their honours either (not to say it doesnt happen but again it would be institution based surely+ their hons must have been pure research over the equivalent time of a masters to qualify surely??-this is based on that PHD are $$ and prestige for most unis....)
I dont know....I based my comments on my experience and research but as I said, it does vary from institution to institution as they all do things differently
my 2 cents worth.............
