Deep into this article the author hits on what is really at the core of steep tuition inclines. A rapidly reducing share of university funding coming from state governments turning once public institutions into defacto privatized universities.[1]
In this chart [2] UWashington lays out in 2013 dollars that total tuition per student has been around 17,000 for 25 years, however during that period the state contribution was reduced from $14,000 to $5000, while student tuition rose from $3,000 to $12,000
> "This is an important shift in who pays for higher education. In 1990, the state provided nearly 80% of the funding per student and UW students paid 20% of the funds. In 2011, the state will pay around 30% and UW students will pay 70%." [3]
