Computer Vs unemployment

i think computer will reduce the forcework but at the smae time will require other force work in other part

Computer applications increase the efficiency of the existing work force. Which means something that may be done manually by two people can be done by one. Now that reduce workforce should mean better profits for a corporation, which means more money to the government to solve problems like unemployment. Obviously all this is in an ideal world. Hasn't computer application or the advances in technology created a huge new sector of work in India. The call centre operations and business process outsourcing then how can one blame computers for unemployment. It is the total opposite.
