When you study Marxist economics you defect with your family to North Korea.  When you defect with your family to North Korea you find you’re in a hell hole.  When you find you’re in a hell hole you redefect to the West without your family.  When you redefect to the West without your family your family ends up in a slave labor camp.  Don’t let your family end up in a slave labor camp:  avoid Marxist thinking and learn to appreciate democratic capitalism.
