Austerity doesn't work in the United States of America either. For example, take a look at the state of Wisconsin. Gov. Scott Walker has cut out collective bargaining for unions and has cut state jobs in the public arena, such as police officers, firefighters, and teachers.
The strategy that Gov. Walker is using is actually a form of austerity. Giving tax cuts to the wealthy by being harsh to the middle class and to the lower class is austere.
Gov. Walker claimed that this type of economic philosophy would allow for job creators within the state of Wisconsin to lower the unemployment rate even further.
However, in one and a half years in office, Wisconsin has become the worst state in records to employment. Over the past year, Wisconsin lost the most jobs out of any state. They were even worse than Illinois and California, states that are virtually bankrupt.
Wisconsin voters were duped because they did not recognize that Gov. Walker's economic plans were actually austerity. If austerity doesn't work in Europe, then it won't work anywhere else.
