At some level

If everyone who goes to college ends up financially better off from going to college, not enough people are going.

There are a lot of kids who have an 80 or 90% chance of doing well. There are also careers that might look financially viable now but end up redundant because of advances in technology.

You don't want a system where going to college can ruin you if you guess wrong on your career. Then again you don't want to make it too forgiving and induce everyone to go.

This change seems pretty minor, and I doubt the details are going to cause a bunch of kids to defer the workforce and get basketweaving majors.
