You can probably mitigate their spread. However, as the poster does seem to want Chinese-style authoritarianism, I can only conclude they have limited experience of what that looks like in reality.

As an aside, I've defended certain versions of democratic socialism (though I'm not a fan of it) to some of my friends that are recent immigrants from China (having worked grown up there and worked in the corporate world). All of them think capitalism and Western democracy is the greatest thing since sliced bread.
