4. imports inadequate in amount and high in price, what are the policy alternatives? Certainly none of the unilateral choices is very attractive. The U. S. could curtail its growth, limiting demand and reducing imports. This brings with it higher unemployment and a lower living standard. Or The United States could strive for mineral self-sufficiency or at least a high degree of self-sufficiency. Domestic supplies could be expanded considerably with a program that removes the inhibitions now limiting domestic development and adds incentives, either in taxes or subsidies of one kind or another. Much of our promising land is now unavailable for exploration and the mining industry has been hit with new laws and regulations that make it more difficult to attract funds for exploration or development. These steps would bring in additional production at a reasonable cost but would still leave us dependent in substantial measure on imports. To be completely self-sufficient may not be attainable and certainly it would not be desirable. The price would be too high as we resorted to increasingly higher cost sources or inefficient substitute materials. We could cause the whole U. S. manufacturing structure to become uncompetitive. So it seems to me we are forced to seek solutions in the international arena and to find ways to assure that the United States has access to raw materials at reasonable prices. I envision an approach along these lines: First, a vigorous and aggressive foreign economic policy that rewards our friends and penalizes those who act adversely to our interests. This would entail acting directly or through international financial institutions, granting or withholding tariff
