Lots and lots of commuters to LA. Then there are the many warehouses in Ontario/Riverside area. They are picking back up, I’ve personally known a few people who were able to get new jobs at these warehouses. Amazon is hiring 1,000 people for their new warehouse in San Bernardino, will be neighbors with Mattel, Sketchers warehouse in Moreno Valley, DHL distribution center at March ARB, Ross warehouse in Perris. High-skill jobs are less prevalent: Loma Linda University Medical Center, ESRI, that’s all I can think of.
The area is definitely overbuilt, so if I owned a house in the IE I wouldn’t expect a major price increase any time soon. The economy will improve though. Even though things have been depressed, the new shopping centers built during the last boom/bust are still chugging along. Many people can still afford to buy their Starbucks, eat at their themed restaurants and purchase cars. Life goes on.
