Sure this is an old thread, however some neighbors have a disregards for privacy, where their dogs poop, noise, and a plethora of other nuisances.
Who puts their trash in front of other peoples property? In this age of being green and the view that over consumption is looked on as a negative trait, putting trash on your property makes it look like you don't feel like you have any concern about the welfare of others.
Also, perception of large families creates another negative view for most people. Either they are on public assistance, not as intelligent as others, or they are very narcissistic, which their superiority is rarely the case.
So please don't park your trash outside my house. If anything I don't want to carry my cans in my house with your roaches, fleas, lice, or scabies, whatever the case maybe. I don't share, or play well with others.
Help to address the problem of emitters of greenhouse gases not facing the full (social) costs of their actions, vote in a carbon tax on the amount of trash you create and the number of children you thoughtlessly bring into the world.
