The currency caste system:

A very small number of rich countries print high-quality fiat (for now) to buy stuff while the overwhelming number of countries can’t and instead have to export stuff *we* want (instead of focus on making stuff they need) to earn high-quality fiat

This currency caste system ensures that most countries never develop sovereignty and instead grow dependency

But! This caste system is completely upended if all countries and people eventually settle in the same global neutral currency that no one state or group of states can print arbitrarily

This is the ultimate promise of Bitcoin: ending the global monetary inequality that enriches a tiny few by causing needless suffering for so many
