Most are $65,000-$75,000/year (except some state universities like Berkeley $55K, UCLA $48K, UFL $31K, UTX $45K, OSU $42K, etc.)

It's not just universities. Top boarding prep schools are even higher, and in my estimation are much more important in terms of developing academic and thinking skills, making the somewhat lesser challenges of university study easily navigable. My Alma Mater, McCallie School in Chattanooga, is now $74,600 ($81,050 international) per year for boarding, $38,800 for day school (It was $1,200/year for day school when I graduated in 1960, and Vanderbilt was $1,500/year for day school when I graduated in 1964.) Choate Rosemary Hall tuition for boarding students is $74,530, and $54,990 to $71,420 for day students. Hill is $81,040 for boarding, $54,980 for day. Phillips Exeter is $71,797 for boarding students and $56,077 for day students. Phillips Andover is $79,800 for boarding students, and $63,840 for day students.
