The largest example would be undocumented immigrants and it seems fairly mediocre. A large portion of the country resents them, there's large demographic/cultural changes, another portion of country/political class wants to provide citizenship/welfare(voiding the GP's calculus), racial/cultural tensions are still issue.

Well heeled thinktanks can continue to try and bamboozle people but after watching every contracting crew in my area become 99% low paid latino immigrant I have no reason to want the same thing to happen to software development when it's one of the few remaining paths to a nice middle class life. I guess I'm supposed to retrain as an attorney or something right?
