Of course, but what the stats are trying to say is that we are approaching a billion total Americans who live now or who have ever lived in this country—all of them, or at least most of them were busy "building" it.
As of 1965 if one were to add the number of immigrants who had lived in the country since its founding, it would only be 47 million. Since 1965, I dont know the added numbers, but suppose immigrates doubled, that still is only less that 10% of those working in this county total throughout history were actually immigrants, the rest were born here, so therefore it is a myth that immigrants built this country, at most they only but 10%.
