The original question had to be edited. I would suggest that Marx would suggest that the presence of globalization would enhance much of his theoretical underpinnings. Marx made the argument that socialism could only work on a large and global scale. The thesis of capitalist wealth had to meet its antithesis of increased proletariat hardship in the widest of scales possible. Once this was seen on a large scale, there could be a broad based movement of workers to transform ownership of the means of production through revolution. Globalization might have provided that for Marx. Capitalism through globalization simply enhances more suffering across the world, expanding the experience of the proletariat.
Marx might well argue that the suffering and exploitation of the worker in China, Brazil, and India helps to make the socialist a struggle a truly worldwide one. It is only through globalization that the statement of "Workers of the world unite" has full meaning. If capitalism was localized in only one or two nations, the workers would not be able see their own conditions and unify. Yet, if workers around the world and across the globe endure similar challenges, there is a greater chance for solidarity and acknowledgement of voice. In this, globalization can be seen by some as actually a way to prove Marx's theoretical premise.
