"If Prime Ministers behave as Prime Ministers, and not as peacocks then you will have change," he said speaking at the 6th Tata Literature Live here.
"On a serious note, change can happen by creating a larger consensus, in a larger constituency," he said.
"It is not that you want the leadership to do what you want, but you want to be heard. The fact that you are not even heard is the problem," he added, articulating his views in a panel discussion of his latest book 'To the Brink and Back: India's 1991 story' which deals with the country's liberalisation reforms in 1991.
"In 1991, both Narasimha Rao, and Manmohan Singh (then prime minister, and finance minister respectively) knew what they wanted to do but they extended their hand of co-operation to all, despite heavy criticism from all fronts," Ramesh said.

"If the political leadership at the top wants change then it must create conditions in which the change is accepted," he said.
He believes a lot of the 1991 legacy was a success but lot of it still remains to be settled.
Considering where the country was poised in 1991, Ramesh rated the industrial policy and trade policy both an "8 out of 10", but the fiscal policy only a "4 out of 10".
"Many years down the debates on the fiscal front are still incomplete. For example, the role of subsidies, role of the public sector, how much of deficits should governments run, are all political issues that are yet to be settled," he said.
He said the leadership should articulate a vision that enables them to participate, and make their voices heard.
