Among the top tier public Ivies, UNC is really the only one even close to the old model. It still gets lots of state support and has a relatively low OOS cap of 19%.
UVA is 33% OOS and UM is 45% OOS with extremely low state funding. UCB and more so UCLA have more recently gotten into the OOS/foreign game given the budget crisis in California.
If you don’t have the old-time state funding, then you really can’t have the old-time mission.
