Bob Marley,
It is true! Nepotism and favoritism works more in US than in Nepal or India.

what  US moral and ethics are you talking about ?Are you expecting moral ethics etc etc etc from Corporate driven USA?Really ask yourself.
Anyways ..lying is not right but consultants do that whether it is white,Black ,brown or yellow.As long as consultants can do the work they don't care as they are temporary and to get work done.
And if you think WHITE AMERICAN MANAGERS DO NOT KNOW THIS AND STILL WORK IN THIS SYSTEM then you are too naive.

Give you an example.A white manager was hired and in less one month he was fired.He did nothing.By the time he was not even out of the work. He had resume made as if he was hero and he shaked the whole company And that too in the same work and using the company's computer.
