Here is the corrected paragraph with the necessary punctuation marks added:
“Let all the learned say what they can—'Tis ready money makes the man.” These two lines of poetry by the Englishman William Somerville (1645–1742) may apply to a current American economic problem. Non-American investors with "ready money" pour some of it— as much as $1.3 trillion in recent years—into the United States. Stocks and bonds, savings deposits, service companies, factories, artworks, and political campaigns—the investments of foreigners are varied and grow more numerous every day. Proponents of foreign investment argue that it revives industry, strengthens the economy, creates jobs (more than 3 million, they say), and encourages free trade among nations. Opponents caution that the risks associated with heavy foreign investment—namely, decreased profits at home and increased political influence from outside—may ultimately weaken the economy. On both sides, it seems, “the learned say, 'Tis ready money makes the man (or country).” The question is, whose money— theirs or ours?
