This "inane question"(gaz)has generated some valuable comments. Fact is the foreign films that get distribution nowadays(and local video release) are the ones distributors find easy to market/most likely to make money(wvq). These are the films on which we base our notion of a nation's cinema(bigpoppa). I try to fight by watching films with no distribution at festivals and buying imported videos(not region 1).
 Current East European cinema is particularly neglected in English-speaking countries. Mexico had a "golden age" parallel to the one in Hollywood, and Argentina and Brasil produced many excellent films during the 60s and 70s that we'll never get a chance to watch.
Having said that, I'd like to hail the French for consistently producing quality films decade after decade, and also for financing films from countries with limited resources. Three countries that have produced some of the most important films in the history of the medium:Russia, Italy and Germany, are clearly no longer as important ("Bella Martha","Bread & Tulips", "Nowhere in Africa" are worth-watching but not great cinema). Great movies are more likely to come out of Iran, Taiwan, and South Korea nowadays.
On a positive note, within the past year or so, three masterpieces I thought I'd never get a chance to watch have been released on dvd in North America:
Fritz Lang's Ger/India co-production "Indian Epic"(1959),
"El Imperio de la Fortuna"(1974) from the great Mexican director Arturo Ripstein, and "Daisies"(1968) from the Czech Republic.
