ELI5: how come that in the Eurozone, places that use the € sell things with tax included but most other places in the world (like the USA) have tax included AFTER purchase?

I think this is primarily an American thing to be honest and your "most other places" is incorrect. 

Australia, New Zealand, Europe, the UK (technically they're still Europe but not for much longer), Indonesia, Thailand, Malaysia, and Japan all do tax as part of the sale price by law. 

They do this to allow consumers more accurate information when making purchases of goods and services.

I think the better ELI5 question would be, why DOESN'T the USA include tax in the purchase price?
