The mere existence of an observed phenomena doesn't imply that some other set of phenomena doesn't occur. It's about determining what can be observed. It's making sure that we don't see patterns where there are none. It's also about making the case of whether the observation is a problem at all, or whether it is just a point of interest and that are goals might be to determine what sort of set of problems we are trying to solve.
In my estimation, the most powerful argument for career obstacles is about competency, pay, opportunity. You need to be educated in order to do anything. You need to get paid so that you can survive, and you need the opportunity of a position in order to get paid. The obstacles from this follow the ordering:
I need to survive, I need something to do, I need to live a life that is not full of suffering (so much that I can even control that), and to do that I need to take on responsibility and work so that there is both something to do, something to reduce suffering, something to get paid for, so that I can survive. I need to be competent because the market pays people based on this notion that you should be educated so that you can actually get any job. Otherwise why be educated at all.
Given this, I would think that the goal of a university would be to reduce the price/performance ratio of a tuition at all possible efforts so that the level of competency can be obtained through quality education at a reduced cost while balancing the incentives such that the resources funnel to the right places where problems can be best solved. In my estimation, this is not even close to what is happening and it's where I would hope things start moving forward - since in large part it appears to the largest possible obstacle for people.
