And it's not just because they are Chinese and believe they are the superior culture. It's also because the Chinese leadership is committed to Marxism/communism.
They recognize that communism doesn't encourage or even permit invention and creativity. They know they have to steal to keep up with the rest of the world in terms of technological advancement.
And that doesn't bother them one iota.
They also recognize that the ideology of communism isn't safe unless it destroys all competing ideologies...hence their absolute need to take over the world.
It does make one wonder where these devoted communists think invention will come from when there is no one left to steal from.
True to their Marxist roots, once the world is conquered the controlling authority of the state will dwindle to be replaced by,,,wait for it...the authority of the people, IOW, rule by the polity, or, the purest form of capitalism. THAT, my Marxist friends, is the end game of the Communist state, to become the culture envisioned by the Founders of the US Constitution.
