President Obama of the U.S. and Prime Minister Brown of the U.K. will be pressing for more so-called stimulus spending by other nations, despite the fact that the historical evidence shows that big increases in government spending are more likely to be damaging and slow down recovery than they are to promote vigorous economic expansion and job creation. The G-20 would be wise to resist such calls for more government spending. Many nations, including theU.S. , have engaged in protectionism in recent months despite the near unanimous view of economists that protectionism will result in more unemployment and lower real incomes. Some members of the G-20 are openly advocating tax protectionism as a form of economic scapegoating for their own failed policies. The attacks on the low-tax states by the high-tax states is as dangerous as any tariff on goods and services since it reduces both the quantity and proper allocation of needed investment capital to revive the world economy. If the G-20 resorts to attempting to punish low-tax states, rather than correcting their own counterproductive policies, it will be a sign of intellectual and moral failure of the meeting.
