Most high tech companies are founded by founded by First/2nd gen immigrants

Out of the top 10, only Google (1 out 2 confounders) and Qualcom (1 of 7 cofounders) I'd count as companies that were built by real immigrants.
Incidentally both are Jews whose families left persecution in Europe (Italy and USSR).
Failure to demonstrate X does not necessarily imply that -X is true :)
I just hate BS - and this chart is mostly BS (ie Jobs is as much of a 2nd generation immigrant as Obama :)
Using that as a baseline (though it has changed over time) means the probability of having at least one foreign-born parent is 25%.
Of the remaining 75%, the probability that at least one of the grandparents is foreign born is 42%.
0.25 + 0.75 * 0.42 = 56% chance that someone in the US is a 1st or 2nd generation immigrant.
Sure enough, "60% of top 25 tech companies founded by 1st and 2nd generation immigrant" is almost exactly what's expected if a company is founded by a single person.
BTW, the table contains at least one error. It says that William Hewlett is not a first or second generation immigrant.
William Redington Hewlett's father was Albion Walter Hewlett. (http://www.hewlett.org/about-us/hewlett-family-history/willi... says that William was born in 1913 and the family moved to California in 1916 so his father could work at Stanford. http://medicine.stanford.edu/faculty/hewlett.html says "Doctor Albion Walter Hewlett, professor and executive head of the Department of Medicine from 1916 -1925".)
The 1910 census record says Albion and his wife were born in California. https://familysearch.org/ark:/61903/1:1:MLTH-RKY . It also says Albion Hewlett's father was born in England.
Therefore, Hewlett is a second generation immigrant.
