Prelude

From my experience, there are differences between co-workers who has a degree and who finished some diploma.  
A person (A) who finished 2 years of BCIT program and started working for 2 years, vs
a person (B) who finished 4 years of BSc and just started working in the same company in the same team.

The person (A) usually get a higher salary than (B) at least for the first few years, but (B) has better opportunities for advancement in long run such as team lead, supervisor, or management level.  Not to say (A) won't get to that level, but when it comes to decision from high management comparing the two , A has 10 years of experience and B has 8 years of experience + degree, the person B has better chance.

I have been observing the mentality differences between a diploma and a bachelor for a while.  In general, a diploma holder is relatively short sighted in projects and decisions.  A bachelor is relatively more open minded and make a better long-run and overall planning.
