Bay Area was just listed second for the most wealth in the US. The mow and Blow yard crews around here charge $400 a month for two 15 minute mow and blow's a month. I do my own yard work I ran rough numbers on the guy who does 4 houses on our street his truck parks in one spot and in an hour twice a month he pulls down 4X$400 - I spoke to him the first year we were here and asked how many houses he had a day. He does between 6 and 8 houses a day. Since then I've spoken to him a few more times BSing about pruning etc and turns out he owns two homes in the next town over. He pulls down more than I do and will probably be long retired before I ever start thinking I can retire.
Different world - when you live in one the top largest economies in the World yes CA is one of the largest economic players in the World - if we could succeed from the US we would be one of the wealthiest places on Earth. The Oil fields we have are only just now being looked at estimated numbers are 50yrs worth of oil that would supply CA and exported. So we haven't even tapped that bank account yet.
I honestly would have little interest in moving to CA. I like how quiet and relaxed pace Pennsylvania is. Pittsburgh has repeatedly been on the top of the lists for "America's Most Liveable City" and "Most affordable city". Through the tough economic times in recent years Pittsburgh's economy has remained unchanged for the most part. There is still a pretty strong job market around here, and housing is affordable. A lot of people still picture us as being a dirty "steel city". In actuality most of our economy is based on banking, education, healthcare, and technology industries. We're very clean. There are a few major pharmaceutical companies in the area as well (Glaxo-Smith-Kline and Bayer North America).
My next door neighbors are from Orange County, CA. Moved here about 6 years ago after living in CA all their lives. They said the only thing they really miss about Orange County is being 10 minutes from the beach. And apparently their townhouse here that cost $90k would be about ~$350k in their area (from what she told me).
