Both Malikane and Diko are educated people whose grasp of economics is entirely theoretical and far removed from the real world. Both have allowed ideology and politics to cloud their common sense. Like Mugabe, who wanted transformation at all costs, their "solutions" will create tremendous suffering for all citizens, but especially for the poor who cannot escape a failed state. Theirs is a scorched earth policy based on entrenched racism and anti-west sentiment, and they do not care if even their own people suffer as a result of such foolishness, like those who have suffered under Mugabe's reign of destruction. 

Both would be well advised to read the classic essay Economics in One Lesson by Henry Hazlitt (Google it to find a free download).

The dangers South Africa faces because of men like this spreading ideas like this cannot be overstated. The DM would do well to consider their own complicity in giving such men and their ideas airtime, if SA becomes another Zimbabwe or Venezuela.
