Of course it is possible today.
I know of a family of immigrant Haitians that moved to the Boston area back in the 1970’s with just a few dollars. The father worked two jobs for few years, and the mother had hers. The grandmother stayed at home with the kids. Today they own 4 or 5 apartment buildings and a small construction company. They had 6 kids and they all graduated form college and now are all lawyers, engineers, or nurses. Very successful family.
