All of the above!!!! However, I believe all started with P.D.P family.  without this evil party run by bloody men , Naiji will be what she claim to be. Also , our Governors should stop planting FLOWERS and DUALISATION of roads that were built by SAM MBAKWE and OBAFEMI AWOLOWO.  They should MODERNISIM, FORWARD and BACKWARD.  We have better TECHNOLOGY now than the days of Mbakwe and Awolowo.  They should think our every year graduates from our higher institutions/NYSC  , use our money built companies,good road network,steady light.......and not CHANGING from NEPA TO PHCN . I think if our leaders should think NIGERIA not  SELF things will be better.   Finally, I must say here without authority from above that , our leaders are evil,cultic,selfish........Rightousness Exalts A Nation,But Sin Is A Reproach Unto People....This The Words Of The Almighty!!!!!!!

the major problem wit nigeria is that we've lacked leaders without integrity and focus,what there are after is money and not how to move this country forward.

NIGERIA is my country but I am not proud of it like some people, nothing for me to be proud of, do I need to be proud of the corruption, power failure, bad roadsbad educational system, no water supply, no good medical, or proud of my co Nigerians who are hungry? if things improve and an average Nigerians can have three square meals, better roads, better education, and better medical services (free) then I would be very proud of this country.
The main problem with Nigeria is corruption, the corruption is everywhere, it is not even in government alone, if you give a Nigerian cash to do something for you, and you come back in the next 5 minutes that you dont want the thing again for a genuine reason, he will be telling you stories, you cant get it back, that is an individual and not a government, nearly every Nigerian is corrupt and fraudulent,  so we need discipline first before anything among Nigerians, this is what Buhari/Idi Agbon were trying to do before Babangida and his cohorts push them out of power, we dont know if Nigerian would have been better now if those two gentlemen were given chance to rule only for about 5 years.
