You are right that most immigrant rags-to-riches stories that immediately come to mind involve them getting off the boat with a handful of dollars to their name. But they seem to forget the value of the college degree that they carry and the lifetime of high-quality education that preceded their arrival in the US. The immigrants you speak of might not be as poor as you make them out to be.
I do not know if many American families can get access to the same resources for early education if they are not already from families that are economically affluent.
