January 1977. We still had wooly mammoths back then. Maybe not...I'm not sure when you went, but my experience is similar. I graduated in 2004. I am an actuary and my best friend's a mechanical engineer. We had identical starting salaries and our annual in-state tuition/R&B/books was slightly less than 25% of our starting salary.
So from 77 to 04 (27 years) the cost to starting salary ratio didn't change much.
But in the 20 years since, it has changed dramatically, roughly between double to triple.
This shouldn't be the case, as cost and salary should move somewhat similarly with inflation.
