Thus far, there is little evidence to suggest that technology will reduce inequality; indeed it may only intensify inequality. Technology is costly and it is generally impossible to introduce advances to everyone at the same time. So who gets this access first As we travel further and further along the electronic frontier through advances such as telecommuting (在家办公) and the Intemet, the poor may be isolated from mainstream society in an "information ghetto (贫民窟) ".Drawing on a survey, the Census Bureau (国家调查局) estimated that only 6.8 percent of households earning less than $ 10,000 had home computers, compared to 61.7 percent of those with incomes of $ 75,000 or more. This issue goes beyond individual interest or lack of interest in computers.The technological advances of the present and future may not be equally beneficial to men and women. Many studies have shown that computer games, which serve as an important means of early socialization to computers, typically involve sports or skills associated with the traditional male role. As a result computers camps have become mainly male settings.Like money, food, and other resources, technology is unevenly distributed within societies and throughout the world. The technology gap is widening rather than narrowing. Although nations are exchanging technical data more freely than before, critical technology transfer is often kept back. The technology exported to developing countries may be poorly suited to the conditions of their economies and workplaces. According to the writer, "information ghetto" is caused by（）

A. the strict control of information
B. the rapid technological advances
C. the complete isolation of the poor
D. the existence of mainstream society
