It's hard to compare them. Harvard includes work-study, but Berkeley apparently includes both work-study and loans (and doesn't disaggregate them).

My remarks above concern financial aid in the form of grants.

It is interesting that Harvard seems to be acting as if it were engaging in price discrimination, even though the traditional conditions don't apply (the supply curve is inelastic, there are partial substitutes available).

Presumably what's going on here is that elite universities want to maximize the quality of students with a view toward maximizing future prestige (and perhaps donations, although the cost-effectiveness is unclear).

I'm having trouble understanding what was intended by "i.e.".

That was supposed to be "e.g.", I just fixed it.
