That might make sense, except that numbers of migrants is miniscule compared to the existing population in almost every case.
For example, Australia has ~200k permanent migrants per year. With a population of 26m. In order for the migrants to become a majority, it would take 130 years to import 26m people. (This is obviously grossly simplified).
There is basically no real risk that we will drown in migrants.
