It is most unfortunate that Singh, who was an economic adviser (to the Centre), Finance Minister and Prime Minister, was critical of the demonetisation move "as if for the appreciation from Sonia Gandhi or Rahul Gandhi", Dattatreya said.
He added that Singh should support demonetisation and promotion of cashless transactions in the country as there is no politics in the NDA government's move.
"These three great men -- A B Vajpayee, Manmohan Singh and Modi -- they are visionaries. I personally respect Manmohan Singh. Modi is doing what he (Singh) could not achieve in 10 years. When Modi is doing, he should give silent support," he told reporters.
"The 'JAM' will bring a revolution," he said.

Modi gave legal status to Aadhar though it was brought in by Singh as Prime Minister, Dattatreya said. "He (Modi) did not set it (Aadhar) aside. Because, it (Aadhar) was in national interest," he said.
Hailing demonetisation as an "economic revolution", he alleged that the opposition Trinamool Congress, Congress and the Left are indulging in mindless and inappropriate criticism on the issue.
Observing that demonetisation would check terrorism, corruption and black money, Dattatreya said the people are supporting the government's move though they faced inconvenience.
He said demonetisation was not a sudden decision and that the Prime Minister is taking steps with a long-term perspective which would benefit the poor.
The Modi government appreciates the common people for their support, he said, adding "all over the country, Rs 3.50 lakh crore was distributed. SBI said this is equal to what was distributed in the last three years".
