USA could stand to have a major update in how it treats currency. As an easy example: why is the penny still legal tender and widely used? Every other first world country had been essentially rid of cent level denominations for years now. Canada is too easy, let’s instead look at Ecuador who uses USD as currency. In Ecuador, outside of touristy areas, salary and prices of everything are in general at most 1/4 of what USA charges. Yet somehow, Ecuador functions without the penny. All prices are rounded to the nearest 5 cents and Ecuador has not imploded from the rounding issues. Why is it that we insist on pricing and dealing with pennies? Every other first world country had adjusted their own currencies accordingly.
