The decrease in net migration has everything to do with COVID + and embarrassing inability to process green card and other immigration related backlogs and almost nothing to do with there not being enough people willing to migrate here. At worst there are tens of millions of people who would migrate here; upper estimates are around 750 million, though that is only based on stated intention AFAIK and the real number would likely be lower.
