In the US, everyone uses credit cards (centralized identity) to pay for stuff.
In Mexico, credit cards are stolen and reamed for all they're worth by criminals. As a result, everyone uses cash (decentralized, anonymous, difficult to use). Everyone could move to decentralized in the face of significant pressure, even if centralized identity is more convenient.
