The Pan Africanist Youth Congress of Azania (Payco) on Thursday lambasted ANC Youth League leader Julius Malema for his "bourgeois and opportunistic tendencies".
Payco spokesman Sello Tladi said the organisation was tired of "unprincipled" tendencies displayed by Malema.
"It is high time that the youth of this country must rise and teach Malema a lesson of life.
"He cannot talk left and at the same time walk right. He is not different from his allies whom he calls 'yellow communists'.
"His bourgeois and opportunistic tendencies have been exposed by his expensive birthday party held ," Tladi said.
"Malema and the ANCYL must be ashamed of cutting an expensive birthday cake while majority of poor African masses that they claim to be representing in Seshego have no bread to cut; busy drinking expensive French wine while Seshego residents have no access to clean water; driving top of the range Land Rovers while people of Seshego have no roads and to cross.
"He proudly proclaimed that he owns two luxurious houses while majority of South Africans have no shelter to stay in while publicly attributing his wealth accumulation to his membership of the ANC.
"The falling bridges that were constructed by his company is a clear consequence of cheap labour, exploitation of workers, and nepotism.
"Anton Muziwakhe Lembede must turning in his grave, when an organisation he served, suffered, and sacrificed for is being used as springboard to petty African bourgeois life at the expense of poor African youth who make more than 40 percent of the unemployed population in this country," Tladi said.
Malema has come under fire in the past weeks for his involvement with a company that won lucrative government contracts in Limpopo.
Several newspapers reported that he bankrolled a lavish lifestyle with government contracts. - Sapa
