There are no jobs, getting a loan is almost impossible if you don’t have a reliable source of income or any property to mortgage, many are dropout, many are graduates with out job, many did not even smell the coners of school, many cannot afford medical bills , many are starving and everybody wants to survive. So i wouldn’t say they are looking for quick money instead I would say they are all trying to survive.
What index are you using fo make these assertion. Last time i checked, most of the things you just pointed out isnt just a nigerian related issue. As much as Nigeria has their own share of the issue, this is a global issue and I don't like the fact that you are making it seems as though Nigerian are the only ones involved in fraudulent activity.
Corruption and unemployment is everywhere so let's not make that of Nigeria look as though it's the worse.
Out population is much and economy isn't all that strong to carter for some of or people but an average Nigerian is an hard working person that can survive in the midst of a hard and tough economy. I know that some of them are bad but their are so many good and exceptional Nigerian out their that are doing great and exceptional things for themselves and I hate it when a shallow minded persons brings up a matter as delicate as this to the public just to tarnish the reputation of a giant nation as Nigeria.
