A Computer Engineering degree does not require ABET accreditation - it didn't when I went to UCSD... the difference between Computer Science and Computer Engineering was just 4 classes. Exactly the same calc/physics classes between the two, which were engineering level.
There are plenty of engineering programs without ABET accreditation. If you get a degree from a non accredited program, you'll likely have a different title than engineers who graduated from an ABET school and will make less. This is because there has to be some standardization in what the people who build bridges learn in school. All companies are different, but my company won't even look at an engineer without ABET accreditation. Even a Ph.D. from China, which is just really dumb. It is reality though.
Interesting. Here's a list of mid career pay by major. Fields that tend to be accredited and value accreditation are certainly present in high places on the list, but variants of mathematics are in comparable places. My guess is that "economics and mathematics" or "computer science and mathematics" are probably examples of fields that require a lot of math but aren't part of an ABET accredited degree. Doesn't look like there's much of a pattern here.
Now, if you plan to work in structural or civil engineering or another field where accreditation is important, than yes, I would tend to agree that having an ABET accredited degree is important (as well as taking the PE exam for that field).
Fields where ABET accreditation isn't terribly important (computational finance, google, facebook, and so forth) often pay more than the fields where it is (mechanical, civil). My guess is that passing the PE for computer engineering wouldn't make a big difference in your compensation at a top tech company, I certainly don't know anyone at those companies who has bothered - though I certainly am willing to evidence to the contrary!
