If you do your "Googling," you will find that Walmart has not ruined Europe.
In fact, England is enjoying their Asda (Walmart subsidiary), and Germany said "goodnight and goodbye" to JohnBoy Walton back in 2006.
As for the rest of Europe, there are still the quaint little shops that we remember from back when, and also the huge supermarkets and street markets with too many choices of everything (especially fresh vegetables!).
So if you haven't visited Europe in the last 10 to 20 years, maybe it is time to go back and see for yourself. Don't believe what you see on some American television networks. You know how they can stretch the TRUTH.
