"The Rich" didn't start the wars, either. Some industrialists do benefit from militarism, but it is the political class with its overlap in the world of mega-corporations, not everyone above a certain net worth.

Corporations are all political creations, legal fictions with legal personhood created under the auspices of government, but most are created as a defense against other aspects of the political system, and few are rooted in the process of plunder directly.

Immigration is not inherently a crime, but the government intervention in travel and trade does create an artificial underclass, and some people do exploit them. The solution is more freedom.
