Trailer living is stigmatized because it's what poor people can afford. With poverty, come all it's correlated afflictions: substance abuse, limited employment, low education and family planning, lack of role models, each determining the other and trapping multiple generation into the same cycle. I.e "trash" people, those who just don't seem to get ahead. Trailer trash is a largely american stereotype because US had a car-centric culture and early economic development that allowed even the poor to buy an RV, while locking them out of the traditional property market. But the stereotyping is against poor people and it's practiced in any society that values material gain.
