The provided material is an opinion piece that argues against “open borders” and portrays “uncontrolled migration” as harmful and costly to people already living in the country. The author presents the view that the negative impacts of large-scale migration are evident and that concerns previously raised by others are now confirmed. The text does not include new reporting, statistics, or named officials or agencies, and it does not describe specific mechanisms or outcomes in detail beyond asserting broad costs to existing residents. It characterizes opponents of open-border policies as understanding these harms, while describing supporters as “crackpots” who may not recognize the impact. Overall, the sources provided reflect a single outlet’s editorial perspective rather than multiple independent accounts of the same underlying news event.
