So the Republicans are ending the department of education, Medicaid, school lunches for kids and vaccines, yet they keep talking about how they want people to have more children

People like JD Vance and Elon Musk keep talking about how they want people to have more children. I suspect they mean children of European origin. Yet these same people are trying to end education, vaccines, Medicaid and everything else that benefits children. Not only that but they also want to end abortion on top of it all. They don't really explain why they want more children in society. I think it's because they want more consumers, but I can't think of any other reason for it.
