Pause,
  If you read my comment more carefully, you'd see that I didn't imply that a Ph.D is "more worthy of job security than other members of society", I said "the over-use of precarious workers and contract-labour has to end". That's a general statement meant to apply to all Canadians. Their are areas where precarious and contract labour may be appropriate, but the majority of jobs should be full time.  That's how it was only 30 years ago, when over 80 of all jobs in the economy were full time. Our economic system has been perverted by lax labour laws. What I did say, however, is that colleges require their teachers to have masters degree's and higher. This level of academic achievement is costly for the employee, so they should be fairly compensated at a level high enough to pay for their accumulated student debt and a healthy lifestyle.
