We moved from California to Colorado in 2011. We were paying $3200 a month in Cali for 1000 sq ft and 1 car garage. We were making fairly good money but it was just gone after paying the bills. Traffic absolutely sucked in the Orange County area to the point that we couldn't legitimately commute more than 10 miles unless we were willing to wait hours on the road (this was before remote work became the norm). We now have a 4000sq ft house, etc at $2400 a month mortgage.Actually, believe it or not I moved to Iowa from SoCal a year ago and as far as income, sales and property taxes my tax bill here is basically a push from California. California's top rate is 9.3% and Iowa's is 8.9%. Neither taxes Social Security. Nebraska's tax rate is lower, but they tax Social Security. The Killer is property tax. San Bernardino County, CA is 0.73%, Mills County IA is 1.28% and Sarpy Co is 2.08%. Granted, the same house in Iowa would cost a lot more in California, so that more or less evens out. My car insurance on 3 cars and a motorcycle is half here, but I never had much of a heating bill there, so that evens out. Gas costs twice as much there, but I don't drive much.
However, our family is here, the roads there are choked with cars at all hours so going anywhere was difficult, and the lowlife activity you mention above has spread beyond various skid rows into almost all areas of Southern California, even previously affluent areas. So we have no regrets about moving here, especially since their whole state is still shut down. My only bugaboo is I have not found a decent head of iceberg lettuce since I moved back here.
The weather was very nice year round and the area we lived in was relatively pleasant, but things were financially too much of a pain. When I first moved there we could get out and enjoy the beaches, mountains, etc but as time went on we had less and less time and money for anything. Things have gotten worse now in Cali and the friends I still have living there are looking to get out. Most have been there for decades but are completely exhausted by the Democratic governance and the overall decline in living standards.
The sad part is that I see Colorado slowly turning into the California I left. The last election was a complete Democratic sweep.
