It's hard to not say that funding is a big part of this. Students are overall very stressed and anxious about their finances. When we're talking about retention of students in general, a big part is student debt once they graduate. We're seeing about 40% to 45% of Ph.D.s graduating with student debt, and that's valued at about $20,000. When we're thinking of them going on to post-docs, as you were mentioning, this is not enough to even pay their student loan payments—along with their expenses. This becomes very troubling for students when we're thinking of retaining talent.
I have to comment, as well, on marginalized groups and under-represented groups. This disproportionately affects these groups, who maybe don't have the choice to take on these lower-income roles. They maybe have dependents or families who also would be funded through these sources.
These are big topics of concern for students.
