How does a banking "monopoly" make the rich richer and the poor poorer?

Question- How does a banking "monopoly" make the rich richer and the poor poorer?

Answer- Anti-Globalizers central claim is that globalization is making the rich even richer and the poor more poorer. Pro-Globalizers assert that it actually helps the poor people. In fact, a substantial part of the decline in poverty had already happened by the mid-1980s, before the big strides in foreign trade or investment.
