My neighborhood would probably benefit from some upkeep ordinances. I spent last weekend ranking my yard, cleaning my curbs where leaves had collected (I also went ahead and edged and mowed my yard though it has already started winter browning).
An hour after I was done, the boy and I headed out to run an errand and the curbs had already collected fresh leaves from the high winds clearing neighbors' yards.
I often daydream while mowing and edging and planting in my own yard that if I ever won the lottery, I would quit working and, among other dreams, in the summer, I would maintain a team of landscapers who I would take door to door in my neighborhood offering to generally upkeep and improve everyone's yards. I would even start a fund to keep it going after I died.
