The reference was to the business that foreign manufacturers are required to bring to Indian firms when a defence deal is signed with the government, under the country's offset policy.
In his address to party workers at the Ramlila grounds here, Gandhi claimed that the Rafale deal had snatched job opportunities from young Indians, including engineers, as the planes will be manufactured abroad.
Gandhi said the price of the Rafale plane fixed now is about "three times" the amount agreed upon during the previous Congress-led government.
He said this corruption by Modi will become apparent over time.
Our youths more honest, capable and stronger than the Chinese but it is a matter of shame that despite having almost equal population, they are getting fewer job opportunities, he said.
He questioned why Rs 2,30,000 crore could be written off as bad loans to 15 or 20 big industrialists, but the government could not help debt-ridden farmers.
When farmers are unable to pay back their loans, they are called defaulters and are jailed. But bad debts of big industrialists are called non-performing assets (NPA), he said.
He also accused the government of failing to ensure the safety of women.
