I doubt that there's any debate that academic education makes for better, more rounded officers.
I do think Worthington (and I'm not usually a fan of his) has a point, to a degree. There seems to be little thought into who gets these qualifications and when in their career they get them.
The example he uses is likely extreme - but still, why does a JAG officer, at the end of his career, need an advanced degree from Cambridge?
I took a quick look at the bio's for senior officers on the DND page (by no means an exhaustive search) and found little evidence that the CF invests education into senior commanders - at least the ones who make it high level command. The CDS didn't benefit from these advanced education programs - so who did?
A family friend (and this is an example my mother constantly brings up when discussing military careers) started as an Combats Arms NCM, and then had the CF pay for his BA and then an MA, and then a PhD - all in English Literature. He now teaches English Lit at RMC, and I don't think saw the field or a deployment in the last fifteen years of his career, or paid for a cent of his education. Probably another extreme example, but they seem to exist - or maybe the rumour mill keeps bringing then to the fore.
I'll second the call for a Canadian GI Bill - easily solve recruitment issues, and give us keen youngin's on 3 yr BE's.
I say degrees for all, and degrees as an incentive to join - and then more degrees as incentives to stay.
Then again... (If I Ruled the World Rant) I'd also shut down RMC as an undergrad institution, have it specialize in advanced studies, send the RMC cadets to civvie uni's and have them parade with local reserve units, and offer Bachelor's and Master's like candy to all levels of the military and as pre-req's to command levels.
