i think it's more of an education and taste issue, than a cost issue. prosecco is clearly a "better" product (by many standards), and usually cheaper than korbel. however, most people buy 1 bottle of champagne a year (and maybe 3 bottles of wine a year) and really don't put a lot of thought into it. i'd guess that this is Korbel's market. i'll also add that it's a decent enough jumping off point for young people. at least it was for me, as i drank a lot of it in college (although there weren't a lot of options back then, and it was clearly a better choice than martini and rossi asti spumante). and if you get a bottle as a gift, don't throw it out or re-gift it. just save it for mimosas.
