yeah you can learn spanish in spain but is less practical to talk put an example between england and the U.S would you admit that the americans speak a better english regarless of where it was first spoken, or would you tell me that to play basketball you have to go to canada and learn it there where it was created and played long before than in the U.S, of course not basketball is played way better in the U.S;
and finally why do you think that the film industry dont use spanish from spain for the trasnlations of the movies?
simple because it cannot be understood by most, and remember that by the 15th century the spanish language was still in transition and very imperfect in spain and the colonies and that the viceroy of each colony order to teach the language to everyone without influence of the other language's spoken in spain like vasco and catalan, thats what makes the spanish from spain deep in accent just like english from britain
