I am sure there are thousands of people in Nepal who are sojo and yet living a descent life.  Not everyone has to be crook to live a good life.  I am sure we can find tons of people in American society also who are crook and have cheated in one way or other to make money or advance in career.  You can probably get many examples in Wall Street. 

We use the terms ghus/source/force in Nepal to get our things done, and I know its pretty common. We can also similar culture in America: for instances, networking for getting jobs, lobbying by businesses to get big contracts and so on.  However, if we just concentrate on doing our 8-5 job in sojo nepali way, we may not be able to step up in corporate ladder in this country.  Those people who have the ability to bring work/expand business ( again issue of lobby may exists) are the ones who will be regarded as successful.  I am not sure just being a sojo in America will give people an opportunity to be very successful in his/her career.
