I think non-business people frequently make the error of lumping all MBAs together; practically speaking, there's a decent gap between the top three programs (HBS, Stanford GSB, & Wharton), the rest of the top 10-15 (Kellogg, Berkeley, Sloan, Booth, UCLA, etc.), and there's a pretty massive gap from there to everyone else.

I think folks often make the assumption that MBA program quality follows a similar distribution to undergraduate education, but unfortunately there's a much steeper falloff from the top few schools.
