The bitcoin concept (what it is, whether it is useful etc.) is still quite complex. I think we can agree that it takes some minimum level of intelligence and perseverance to figure these things out.
It could be argued that with FIAT currencies the poor had a hard time getting rich and as such there was a demographic divide with limited social mobility. For example, someone really smart might be born into a situation with tough chances of being financially successful.
If Bitcoin succeeds it seems the intelligent and the early adopters has a huge advantage already. As such, the 'injustice' is still there it has mere shifted demography.
This insight is a very real possibility, but I think you're overlooking something important. Political power has never before been granted on the basis of raw intelligence, benevolence is not unlikely here.
I think often about how global bitcoin adoption might be humanity's first step toward transcending capitalism. I imagine hundreds of suddenly super-rich smart people begin funding new types of schools, which focus on critical reason, empathy, civics, ethics, ecology, and conflict resolution skills. Most modern nationalized schoolsystems teach obedience and conformity first and foremost, with bureaucratic dogma one-size-fits-all teaching systems that force kids to memorize and regurgitate information on command as if these young minds are military trainees or zoo animals.
I mean this very seriously:
World Peace and permanent environmental sustainability are both possible in a future when we teach our children to distinguish the Stuff That Matters from distraction bullshit.
