According to sociologist Georgy Derluguyan, the Checheno-Ingush Republic's economy was divided into two spheres—much like French settler-ruled Algeria—and the Russian sphere had all the jobs with higher salaries, while non-Russians were systematically kept out of all government positions. Russians (as well as Ukrainians and Armenians) worked in education, health, oil, machinery, and social services. Non-Russians (excluding Ukrainians and Armenians) worked in agriculture, construction, a long host of undesirable jobs, as well as the so-called "informal sector" (i.e., illegal, due to the mass discrimination in the legal sector).
