Socialism must be secure before communism can be realized. Which will mean not only ensuring the entire world is developed, everyone has superabundance, all major deadly conflicts are largely resolved and interracial, interethic, and international grievances are healed, and the lingering ideologies spawned from America's international brainwashing operations have been excised, but then we will have to deal with our first major related challenge as a unified species: climate change.

I mean, nothing will suddenly switch overnight, as the world becomes more socialist or even more internationally interested in peace and cooperation, borders will become more porous. Death of US empire alone will see to this beginning.

Calling borders "bourgeoisie" comes off to me a little weird.
