Is Globalization good or bad?

Today in class we talked about the pros and cons of Globalization.  For a place like America Globalization is great, but for developing countries like Indonesia globalization is not so good. One Pro is, it is logical, "natural" expression of modern international capitalism. Also wealth will trickle down from rich to poor countries and that new ideas and technologies will spread around the world. However globalization is a policy promoted by core countries. It results in inequalities between "haves" and "have nots". Also it is just not working; In the last 20 years, rich countries have grown richer, while the poor have become more impoverished. This all shows that globalization only works for some countires.
