I don't think you can make a blanket statement like that. I come from Ireland where I received a 4 year degree in CS for free. Most of the Americans I worked with over the years are saddled with huge amounts of college debt. This is a massive advantage in my favor.
Having to spend 4-6 years waiting for a green card so I can start my own company is a massive disadvantage. Having to deal with the annoying vagaries of the US immigration system just to get a job is also a massive disadvantage.
Coming from a country that has good free high school education is a massive advantage compared to most places in the USA.
Having parents who are financially well off and can support you while you are in school is a massive advantage. Having parents who went to university and can tell you the difference between schools or guide you through the byzantine application processes are massive advantages.
