> Imperialism is not capitalism, they are orthogonal concepts.
I would argue they are very tied, but that is a much larger argument not needed here. To give the short and incomplete version, they are both derived from the idea of exploiting others for profit. The level of exploitation is just much less in capitalism and masked behind the guise of fairness, ignoring power dynamics, original capital, and exponential growth considerations, etc. Again, this argument is very incomplete as stated here, but they are not orthogonal concepts. How much of a connection they have is a very valid debate, one not needed here fully though.
> extreme poverty has been shrinking. And now we have the mechanisms for almost anybody to get out of it.
Getting better does not mean that everyone can get out of poverty. We also haven't gotten that better. Most of Africa is still being exploited and most living there do not have any realistic means to get out of it. The countries as a whole still struggle on a macroeconomic level to get out of poverty due to the exact exponential growth issue seen in Bitcoin but with general investment.
The US is not representative of the rest of the world, and also is still far from equal opportunity. While we're on that subject, good luck easily buying cryptocurrencies (accessible to a non-tech audience) while living outside the US. Even my Canadian friends struggle getting Coinbase to let them.
Bitcoin is only really accessible to the tech community, an already privileged community.
