They will just divert funds from other places to cover the illegals.
example:
The Department of Health and Human Services has diverted more than $2 billion meant for other health initiatives toward covering the cost of caring for unaccompanied immigrant children, as the Biden administration grapples with a record influx of migrants on the southern border.
The redirected funds include $850 million that Congress originally allocated to rebuild the nation’s Strategic National Stockpile, the emergency medical reserve strained by the Covid-19 response. Another $850 million is being taken from a pot intended to help expand coronavirus testing, according to three people with knowledge of the matter.
Yep! You beat me to it, I saw this bit of news and thought to myself that this was the beginning of the end for the US economy or US dominance in the world. No wonder why the Deep State thugs wants to start wars in the world.
