Global capitalism will not end all war
Global capitalism will replace ethics with greedy CEO's and will create a plutocracy. This dystopia will not end all war, but it will create a terrible society where the rich rule and the rest become oppressed by the oligarchs. This is hopefully not what the real Jesus planned. Millions of people will be deprived of their basic human rights, the wealthy will become wealthier, and the econmic gap will grow bigger. Programs such as WTO are already making this horrible idea come to pass. We don't need more inequality in this corrupt, authoritarian world. I think uniting the world and freeing everyone from countries is a great idea, but not like this. If this idea fully comes to fruition, then it will probably make capitalism worse (if that is possible).

Perhaps with all the extra money going around we can all build ourselves a big pyramid dedicated to the corporation, Duncan The Church of Dim Sum

The concept of a global corporation is already here, turning the world into a giant corporation would be atrocious. The corporate empire is already here. It even has the State to support it with laws. The "free" trade actually enslave millions, no point in extending it. Most multinational companies exploit natural and labor resources. Capitalism and hiearchy need to be completely abolished.

And what would you replace it with?
