Arthur Eze has been a major philanthropist since the 90s. He is an extremely wealthy man. How much does it cost to sponsor a "primary" gubernatorial candidate in Anambra?
Also, what has this got to do with Biafra? For some people, they'll rather be in a corrupt Biafra than in a corrupt Nigeria. Most people will choose self determination even if they will be financially worse off. That's just a fact! Look at the case of UK and the EU; they will definitely be financially worse off for years (if not decades), but majority prefer that rather than be controlled by others. Anybody who prefers being controlled by others, no matter the financial incentives, needs to have their heads checked.
