The article is about immigrants. The parents of immigrants don't live in the U.S, so it's extremely unlikely that they got property through inheritance. (You can't apply statistical conclusions about a large group [all Americans] to individual subgroups [Chinese immigrant waiters & home-care providers] without adjusting your priors, and in this case there is a very strong prior for "parents did not own property in the U.S.")
