Nothing artifical at first. First people will make a political choice early on by dividing into two revolutionary camps. One: neo luddite, second: technophiles, As technology rapidally advances into the 21st century. Now If the neo ludditism revolution wins we will without question remain stagnant in a political belief system for years and years to come, but there will be a catch this time around because science will be abolished. Which in this case scenario neo-ludditism will collectively govern societies close to the primitive sense of the word. However, if that were to occur i'm fairly optimistic people would start to see the error of their close to primitive ways for abolishing scientific technology. And as the earth begins to become uninhabbitable due to its inevitable life span in our solar system they will change course and revolt. Now, if the technophiles win the revolution political beliefs as you and I know them today will ceases to exist. Instead humanity will be focused on making unison decisions on how to best financially advance nanotechnology, space explorations, terraforming, and genetic engineering. Thus, Altering humanities future from surrogate activities to actual accomplishable goals for humanity. So Instead of having political belief systems humanity well be united and directly focused under a technology and economy surplus umbrella system to better help further the goals of space exploration, genetic engineering, and terraforming planet projects for humanity. It's not a matter of classes per se to me, It's a matter of human survival. Mars and/or venus will be like a kin to mother earth and as such so will the new human species that evolves on there. And the earth citizens that moved to Mars and/or Venus will be the next step in the human evolutionary process. These trips to mars and/or venus will be made little by little by earthlings until the process of moving from the earth to mars and/or venus is completed. We are moving toward a umbrella-like economy already with programs such as Nafta and the eurasia-america transport link. It's only a matter of time to me, to each their own though.
