How did beveridge imply that domestic economic concerns were dictating american foreign policy?

Early in his career, Albert J. Beveridge (1862-1927) was a huge promoter of American overseas expansion.  He argued that the USA needed to find new markets in the world for American goods, for the good of American businesses and investment and to provide greater opportunities for American labor.  

Later in his political career, however, Beveridge began to change his positions, becoming more of a Progressive in American politics.  He began to advocate the regulation of big business and push back against the hefty influence of business on politics.

So depending on which part of Beveridge's career your question is talking about, the answer you might want to give would perhaps be different!  Beveridge moved in a different direction beginning in the early 1900s from what he had been saying around the turn of the century.

The goods the europeans wanted the most were gold, jewels, silk, perfumes, and especially spices.
