Kebab Crisis, Lucca, Milan

In an effort to preserve the "culture" of Italy, small town Lucca placed a ban last year on any new restaurants, cafes or bakeries opening that don't serve all Italian food. This has had a big impact on the hundreds of kebab vendors who roam the streets of Lucca and now Milan. They are struggling to find ingredients that satisfy the "all Italian" label. It has been difficult for officials though to determine what food is foreign, and what is authentically Italian. They seem to be letting French cuisine slide, however bans have been placed on the importation of all Chinese vegetables. Truthfully though, Italian food has been contributed to from Chinese and Peruvian cuisines alike as well as many others. What are the implications of this for the rest of the world? Will we eventually become so wrapped up in our own cultures we will outlaw all foreign competition?
