Today there is no evidence of job creation. Quite the opposite: unemployment is rising and millions of jobs have disappeared. In place of thrift we have become a nation of debtors, staggering beneath mortgages that exceed the value of our homes, and credit lines that exceed our ability to repay. But the "Great Recession" has also changed the nature of unemployment, making it harder for those out of work to find a job. Only by investing in infrastructure and innovation can we mend the system.
