单项选择题 __________ With half of all homes being priced above the half million dollar mark and prices in urban areas such as San Francisco and Los Angeles being higher than the state average it is almost impossible for not just the poor but also the lower middle class workers to afford decent housing and no possibility of home ownership. The majority of the population lacks a college education, and the median home price was determined to be $723,790, requiring an upper middle class income which only roughly 20% of all households in the county boast. Such fluctuations in local markets are however not considered in the Federal poverty line and thus leave many who live in poverty-like conditions out of the total number of households classified as poor.
