Other countries such as Canada, Brazil and Australia (and to a lesser extent many others) were colonised at a similar time to the USA and all have had similar advantages (high population, a wealth of mineral resources and huge amounts of land) and problems during their histories (difficult relations between settlers and natives, struggle to gain independence, huge wildernesses dividing the country).
Up until now out of the countries that used to be known as the New World only the USA has emerged as a major world power. What do you think set the USA apart from other countries with similar beginnings?

I have a friend in Brazil who is in their 3rd year of a 5 year degree program in Mechanical Engineering. They would like to move to the USA and are looking for colleges/universities that accept transfer students from Brazil. Any city is fine. Thanks!
