I think I would take an imaginary country...using all the current and accurate statistics...and tell a Paul Harvey-like story (”If I wanted to dismantle a society, this is how I’d do it”).
So you tell it from this prospective...that it’s not just 100,000 or 200,000....but that within five years...it could be a million a year.
So the federal government would manage this...by systemically moving them around. It wouldn’t make any sense to send them to California or New York state...so you send them onto Iowa, Mississippi, Georgia....and onto various voting districts.
You’d plot this out...taking over voting numbers of close Republican-Democratic districts. Then after a while, without telling your helpers...you’d then start to mass the groups in black districts and heavily black urban areas.
Your agenda doesn’t have anything to do with society...but with degrading what exists already.
The MS13 drug crowd? You kinda get to the end of your paper and just laugh....as you were paid by MS13 to make all this political agenda stuff happen, but it really doesn’t have anything to do with democracy or saving the kids or violence in Central America, or even with rigging up Democratic votes. It’s all done...to make MS13 a household product and name in America. Tell the story as Paul Harvey would tell it.
Richard Lamm's writings would be a good source to consult for that.
I love that idea of doing it as a fictional country. I don’t think it would work for this particular assignment, but it would be great as a creative piece.
