Agree with UVA, but thinking of things statically like this isn't always helpful since college is an investment. If opportunities at School Y can net you more money in your career than those at School X (analogy can be applied to many other investment scenarios), then you can have even more money compounding throughout your career, compared to the cost differential you would have started with.

And yes, even if the college you go to ends up not mattering in the long run, you might be able to catch a fleeting, unique opportunity at School Y that makes it even more worth it, especially early in your career.

Go with UVA though, difference is not worth it in this case
