In the case of South Africa, the shortage of wateris very real. The people will rise up against the politicians for their careless mismanagement of the situation. The smart way to head that crisis off is to blame the white farmers at the precise moment when you need to divert the masses from the shortage of water. You always have to create the enemy. In Germany, it became the Jewish banks, then the Jewish merchants, and finally, all the Jews. Before that, to save money, the German state began to execute veterans from World War I who were costing too much money to maintain. They took them from the hospitals and executed them.
Make no mistake about it, if the Democrats gained control of Congress and the White House when the budget goes into crisis, they would be confiscating property in the United States as well. Even during the American Revolution, they actually issued paper money BACKED BY the confiscation of property of anyone who supported the king. Humans will act the same given the same set of economic conditions.
