I disagree with you patientrenter. California will experience a slump as other areas of the world are developed into attractive destinations with higher growth rates.
Immigrants come to California because the opportunities here were greater. But as other parts of the world achieve parity with America, fewer immigrants will come. Europeans came to America during periods of war and famine but now, few Western Europeans want to come here. Poor immigrants aren’t going to prop up the prices of mc mansions.
