I disagree.
My daughter was an economics major at a large research university. Her experience differed from that of economics majors at liberal arts colleges in two important ways:
(1) Many of her classes were quite large, mostly because students from other colleges were in those classes with her. For example, she sometimes shared classes with students from the undergraduate business program.
(2) She had the opportunity to take courses in subjects outside the liberal arts college. By the time she graduated, she had completed two finance courses, two accounting courses, and an entrepreneurship course, all from non-liberal arts divisions of the university. These courses were very relevant to her career plans, and she was glad of the opportunity to take them.
In her opinion, the advantage of being able to take courses outside the liberal arts division of the university outweighed the disadvantage of the larger classes. Others might disagree.
But in any case, the experience was different from that of a student at an LAC.
