1) Grade inflation does not take into account the quality of peers. It is easier to be in the top 10% at crap U than it is to be in the top 50% at tough tech, even if the top 20% is an A at crap U while a "generous" top 30% is an A at tough tech. Grades will still be "inflated" at tough tech, but they will still be much harder.
My experience is that it isn't true. Having been to both, I'd say that it's considerably harder to get though as a physics major at University of Texas at Austin than at MIT. The thing about MIT is that it just does not weed out physics majors so that you end up with 90+% pass rates in the intro physics courses. UT Austin did try to weed out physics majors when I was there, and so you had much, much lower pass rates.
The thing about MIT is that you can be in the bottom 20% and still survive, whereas this did not appear to be true at UT Austin.
That same kid, with that same amount of work, would have gotten lesser than perfect scores at the harder school, maybe significantly lesser than perfect scores (significant enough so that they have very little chance at getting into a top tier school, whatever that is).
You aren't going to get anywhere near perfect scores at MIT. The tests aren't set up that way.
Now, consider another kid, who could get a 4.0 both at the easy school and the hard school.
As far as the amount of work that you have to do to survive. UT Austin is considerably harder than MIT.
There's NO way to differentiate, just from the GPA, if you have a "very good" 4.0 kid from an easy school, or "would have been a 2.0 at a hard school" kid from an easy school, which is why you're forcing grad schools to take a second look.
Which is why if you have decent grades, GPA is not a hugely important factor for getting accepted into grad school. There's too much variability between schools to tell what a GPA really means.
You might have a better chance being the 4.0 kid at the easy school than being the 3.5 kid at the hard school because they could mistake you for the possibly 4.0 kid at the hard school (here's where the other parts of your app are huge) whereas had you actually gone to the hard school you'd be identified as the 3.5 kid, and gotten tossed from the Harvard waitlist.
1) You are just wrong about how graduate school admissions work. Committees are aware that people will try to game the system this way, and so GPA isn't given a huge amount of weight. What matters is less what your grades are than what courses you take, and you really want to take nasty, hard courses.
2) You are assuming that MIT is a "harder school" than most state schools, which just isn't true. Two people with equal ability taking physics courses is likely to get a much higher GPA at MIT than at most public universities. MIT doesn't try to weed out physics students, whereas a lot of large public universities *do* try to weed students out. I have the advantage that I've taken courses at MIT and Harvard and I know how inflated the grades are compared to most public state schools.
Also I think you are very, very much mistaken about the caliber of students that take physics. As far as math ability and general competence, I really didn't see that much of a difference between the people that signed up for physics at UT Austin and those that majored in physics at MIT. The average MIT student is probably mathematically sharper than the average student at UT Austin, but when you talk about physics and math major, you've got a self-selected group, and I didn't see that much of a difference in the caliber of student.
This is important for the most part you don't learn physics and math from the teachers, you learn it working through problems with other students, and if you surround yourself with people that are somewhat smarter than you are, you'll end up learning more.
