I just met a Nigerian computer engineer preparing to get into nursing school.Why, you would ask. It is because he is having a very difficult time getting a job in his field he says. He emphatically narrated of the many times he has found himself on second or third interviews with numerous companies in Boston.He said it always ends with him seated next to a young white man who gets this job and he doesn't. Always.
The man from Nigerian tells me that, nursing is the only color-blind career he believes in right now. I believe he is right. It is no wonder then that so many of people from the continent take this easy route. Many people do not have the mileage to fight their way up the corporate ladder, that is in terms of time and resources. These are the people who, forsaking their other hard earned degrees switch to this career that pay three times minimum wage with readily available jobs.
I guess this answers the questions many others ask.
