Being a parent or being childfree isn't a class issue but renting v. homeownership is.
SoutheastEze did say that 'Perhaps a lot of the foulers (if you excuse the pun) are not homeowners or do not have children so are perhaps not as aware of the health consequences or do not feel much long-term attachment to the area and its cleanliness?'.
While I appreciate that this poster is temporarily renting themselves, I do not like their insinuation that renters/childfree people care less about an area. I have come across some real neighbours from hell who've been both homeowners and parents. And the opposite.
