"In the long run the prices would come down, so would the inflation. The growth would kick start, the jobs would increase. There will be increase in exports too. It (GST) will be a game changer," he added.
Jaitley emphasized the need to increase production to create employment and get taxes and use them for social security and development.

Union Parliamentary Affairs Minister M Venkaiah Naidu said that government is making all out efforts for the passage of GST for the common good of the people.
