Hi picklee,
I understand your concern about persons wanting to 'jump to PR without offering something', (I'm not a fan of people who exploit systems either) BUT...
...While I'm sure many persons would LOVE the opportunity to pursue a Master's in Canada, unfortunately, not everyone is going to have the opportunity to go to Canada to pursue a Master's. As 'reasonable' as their graduate rates are, Canada's graduate tuition rates are still fairly high in comparison to other countries. We have to be cognizant of the fact that not all paths are available to all persons, and we have to work with the cards that we are dealt (without potentially belittling the deck of cards dealt to and paths chosen by other persons

). For my own situation, I have a good job in my home country, have been earning well, and have MUCH more savings that my average country-man, and it would still be a stretch for me to afford a Master's Degree programme in Canada, especially under the international student rate vs. the local rate that would be afforded to me as a PR.
You stated that "The fact that you have tried and failed to get a job before indicates that you might need to change your strategy"...but, I don't know that The Wall's difficulty in getting a job offer in Canada is an indication of how much he'll be able to contribute to the Canadian economy. (
The CRS Score, might be an indication, based on IRCC's reckoning, but not the inability to get a job offer). Canadian employers understandably are going to be wary of someone who doesn't yet have work authorization, and who doesn't have Canadian work experience, but it doesn't mean his current skills and experience wouldn't enable him to contribute positively to the Canadian economy, and that he won't be able to find a job ONCE he has PR and the subsequent work authorization that goes along with it.
I'd like to believe that most persons who apply for PR through Express Entry without pursuing the 'studies-route' ARE trying to offer something to the Canadian economy. (
Granted, our own assessments of what we can contribute may not align with IRCC's assessment of what we can contribute, per our CRS Scores, but that doesn't mean our hearts aren't in the right place 
). We may not have a Canadian Master's or Canadian work experience, but we do have foreign credentials and work experience that we think can contribute positively. And while I understand that it might ultimately make our paths to setting in Canada a bit harder, it doesn't mean applicants who pursue this route won't be able to contribute something in their own unique ways. In fact, if the Canadian government didn't think people like us could contribute to the economy, they wouldn't have the Federal Skilled Workers programme in the first place - they would require everyone, instead, to come and pursue a Master's first.
I should also note that I actually know a lot of people who use the 'studies' route as a way of
circumventing IRCC's assessment of their potential contribution to the Economy, because they actually couldn't get through for PR through Express Entry. So some persons who choose to pursue studies in Canada first rather than the direct-to-PR route of Express Entry, could be just as "guilty" of trying to 'get to Canada without offering something' as someone who applies through Express Entry for PR because they don't want to or can't afford to do a Master's
