Thousands of Poles migrating across Europe and North America in search of work and higher wages should not overshadow the true image of Polish diaspora. Due to their industriousness, entrepreneurship, determination, and tendency to save and invest prudently, Poles were already the third wealthiest ethnic minority in the U.S. at the end of the 1970s. They were only preceded by Americans of Jewish and Japanese descent, but surpassed those with Chinese, Italian, German, Anglo-Saxon, Irish, Filipino or East Indian roots (source: U.S. Census Bureau and the National Jewish Population Survey; see: T.Sowell, “Ethnic America”, ed. Basic Books, 1981).
Studies at the start of the 21st century have shown that Poles, in addition to Americans of Jewish, Scottish and Russian origin, continue to be one of the wealthiest ethnic minorities in the U.S.
It is a similar case in Canada, South America, Australia, South Africa and certain Western European countries.
