During an interview with Sun Newspapers, Kalu recalled that Nigeria's economy once entered recession at a point in 2014, absorbing Buhari of the blames of the 2016 recession.
"The problem is people are envious and jealous; they see Orji Kalu who is rich, but they do not know what I have gone through to get to this level. They want to be like me, and that is not possible.
"I'm calling on Nigerian youths to be of good use to themselves.
"Let me be honest with you, I cannot judge Buhari. He has a four-year mandate to turn things around. He still has time and I expect that he will do something. Young people might be feeling frustrated. Government must not do everything.
"The only thing is that government is not paying enough attention to the manufacturing sector. If I am government, I will pay attention to manufacturing and agriculture. You pay attention through the entrepreneurs by giving them single digit loans and opportunities.
"All the enterprise done by government will not work until they see us as partners. When Dangote was starting his cement factory, he was encouraged by the government. Today, he is all over Nigeria."
