However, checking the past experience of the applicant -- which seems perfectly reasonable for the hiring company to do -- would still allow discrimination against older Americans and foreigners. I'm not sure how that could be fixed even with anonymity.

simple: You don't write all of your experience in your resume, only the experience relevant to the job you apply for. They want 5-7 years experience in Java? List only your last two Java jobs, don't mention that you did 15 years of C++ before that.

That's easy for someone who's worked at many different companies. What about the applicant who's primarily worked for a single company for many years? This is much more likely to be true for an older applicant. Do you lie about how many years you worked at the company?

Regardless, it still doesn't solve the problem for foreigners who may have only worked for companies outside the US.
