Corile have good point about immigrants. This is also why im personally try take away that "bloody communism" memeing from coalition factions - nobody wouldn't immigrate from houses with good level of life to far and dangerous systems to be killed by aliens.
But, there Core have justification, they just cannot say it right. Core and Order factions more about ideas. Like Core about their right wing ideology to get supremacy and Order with their conspiracy work to preserve humanity. People can join to Core because they dont have much of ideas inside of Houses.
Btw, this is not so much of peoples how you want, but yeah, they still exist, because everytime will be humans which seeking frontiers and supremacy.
Also, i think much more important way to making money for Core should be APM shipbuilding for corporations escorts and paramilitary parties. In free houses always exist place for bunters, so think Alabama should make money for producing snubs and gunboat from junkers scrap. Im just think, in really core guys can try adjust half or even more of their claims, but they just too fascinated by shiny nomad iridium things.
