As to your education being the lowest, what I found was exactly the opposite. I looked at about six graphs and Education was the highest on all of the charts.
Now, I have a couple of advanced degrees in educational areas and I am not even a little impressed with those graphs.
I remember from my undergraduate time that most education classes were notoriosly easy and consequently those students majoring in Education were often considered slakers.
I was a prelaw student and didn't pay much attention to other fields.
I found that law school wasn't what I was looking for and wound up back in school doing teacher certification requirements.
I just kept going and finished a MS before I went to work and I believe the work I did was substantially less demanding than was the material I dealt with in pre law.
The masters degree particularly seemed to fit the often heard description of the work- pay the fee and get your B
Because "journalists" suck at math, and don't understand the concept of negative numbers.
