But its the trend that is potentially devastating for the middle class. If you look at the totality of "knowledge jobs", there is a potentially huge number of them that can be done overseas. Look across disciplines in many industries, basically any job that can be done by someone sitting at a desk with a computer, whose physical presence is not needed, can be done overseas. Extrapolate that, and you can see what the potential effects on the white collar private sector middle class can be in 10 years. We've lost most of manufacturing, if we lose "knowledge jobs", we'll have just service jobs and government jobs left.

Whatever you extrapolate will fill the hypothetical universe.

the same was said when people extrapolated decades ago about manufacturing. We are in our 42nd consecutive month of declining manufacturing employment. While manufacturing has different considerations then knowledge work (declining numbers of workers due to automation), the trends regarding US manufacturing are not in dispute.
