Fourth generation San Diegan and Californian here
TLDR: California especially Southern California is a very pleasant place to live. We've lived in San Diego for four generations and most of our family still calls San Diego home. The cost of living, home prices, and taxes can make it a challenging place to be but we love it here and plan to stay.
Southern Californian's enjoy one of the most pleasant year-round climates. Within two hours of San Diego are mountains Palomar Mountain at 6,100 ft, Cuyamaca up to 6,500 ft, desert Borrego, tons of beaches, Mammoth is six hours away, Yosemite is 8 hours away. Our semi-arid Mediterranean climate is pleasant year-round and only a handful of cities have a similarly pleasant climate The Canary Islands, Spain’s Costa del Sol, Sao Palo, Sydney, Medellin, and Lihue has similarily pleasant year-round climates. We're generally a diverse, tolerant, and multi-culturally oriented. It's progressive and liberal with some pockets of conservatives.
We also have our challenges with affordable housing and the high cost of living. Prop 13 which fixes your homes sale prices as the tax rate plus an increase of up to two percent a year. So you get folks with absurdly low tax bases sitting next to folks with market rate tax bases. Plus businesses are included so you see apartment building or other buildings with very low tax bases.
It's not perfect here and San Diego home prices and cost of living combined with what we call the Sunshine tax or lower wages in San Diego can make life tough. San Diego's wages and cost of living and housing prices are more out of wack than LA or other cities but where the cost of living and homes is high but wages are generally higher.
