Western Europe has always been cleaner than both Eastern Europe, and the US, but things have been backsliding. Things have recently changed for the worse. eg. I was in Paris, and I could see a stark contrast between now and 10 years ago. Also, parts of Italy seem to be backsliding, and then you have parts of Croatia that look better than many western parts. Ps. In the US, NYC and SF are pretty 'dirty' overall, but then you have mid tier cities such as Miami, Boston, D.C., that are and feel very clean overall.
