I wouldn't say they are low IQ. Some may very well be quite smart but they have little to no education and no marketable skills. It's literally like trying to assimilate millions of children all at once. They bring nothing to the US except for their "potential" to perform jobs that uneducated and unskilled people qualify for.
A personal story from my time in Big Pharma.
I was the jack-of-all-trades I.T. guy at Merck Animal Health's distribution center for 11 years. Just about every non-white worker in our distribution center was an immigrant from the African continent. They were some of the hardest workers I've ever been around.
As with other immigrant communities, these guys came from nothing. One guy left his home country (I think it was Sierra Leone) for another African country due to war and famine. Only to have that country devolve into another crazy war. At that point he said, "Enough is enough". Brought his family here with the shirt on his back.
I have talked about it here before, but my wife came to this country with her Mom, sister and niece. $20 to their name. The Armenian diaspora from the war and genocide in Azerbaijan. I haven't met anyone from that community that wasn't a hard worker, and what they have now is due to that hard work.
This country was built by such waves of immigrants.
