They never had any edge from the onset.. They only overtook Igbos after the war, now Igbos have displaced them back to their normal position in Education..
Before the war, they struggled and did everything humanly possible to meet up with Igbos in Education, Awolowo even went as far as declaring free Education for them to meet up, when Easterners were paying a lot of money to go get educated yet all to no avail,.
They only managed to overtake after the war. Now Igbos have taken their rightful position leaving them to compete with NE and NW like it was in 60's..
The same thing is happening in other sectors, let them keep gloating for now, one day monkey go go market e no go return like it happened in Educational sector..
