Cloward and Piven. Allow uncontrolled immigration to overload the system to help collapse the government.
Yes, but that is only the first part. Orchestrated crisis is supposed to collapse the system so people will be disillusioned with the free market system. The second part is that it is planned so people will be in such despair that they will grasp for communism to save them. It is all planned to usher in communism which has always caused more death and suffering (at the hands of tyrants) than any other economic system.
