Los Angeles county: Traffic, punishing heat most of the year, no seasons, no festivals, uneventful days. Cracks in the sidewalks, graffiti, gum stains everywhere, except when the bums sit on these blemishes. Cheap functional architecture makes for ghetto scenery. Widening rift between the rich and poor means the best looking buildings are McMansions on cliffs by the coast, while downtown, city hall, and the public libraries look like temporary structures built in the fifties. Pathetic mass transportation due to the car industry lobbying to remove the railroads and cable cars in the west.
Bilingual means Spanish takes up the signs, and Mexicans give worse service at restaurants unless you're a Mexican. Poor customer service, and retarded baby-talk languages like Chinese, Korean or Vietnamese when you're curious enough to eavesdrop.
Crumbling public infrastructure and public educational facilities. Occassional smog, sometimes from wildfires. Constant police helicopters, flying colors, violence and policy failure in the local news. Shallow materialist types, especially whites and UCLA asians. Their favorite news is entertainment, which deals with the personal lives and careers of Hollywood celebrities on par with insignificant high school clique gossip. No nature, nowhere to be alone or breathe fresh air unless you own a car and drive for hours. Unfriendly people, but they don't put on the fake smiles and polite greetings like in Orange County. Bad parks. Literally nowhere to go, and nothing to do in the suburbs except waste money shopping, or on coffee or boba milk tea.
Orange county: stuck up white people and most of the other problems. Fewer gangs than LA County, but more blatant bullying at schools. Every other neighbor is part of a Evangelical Christian club of hypocrites riding on high horses and Armageddonists. And it gets worse: Persians (Muslims) are moving in. Fake people who smile and say hi when a stranger passes or walks into a building, but are unfriendly and uninterested in conversations. Bigger parks, but still boring and a weak sense of community. Every kid under 22 is a gamer/quasi-loner or on drugs.
