I don't think anywhere does. In general, cards in Europe don't really give significant rewards (because interchange, paid ultimately by the merchant, is capped at 0.3%, whereas in the US it can be upwards of 3% for certain high-end cards). The only reason that people who don't need the credit line use them in the US is the rewards schemes.
That's not what GP said. They claimed that "everyone" in Europe uses debit cards, and that's just not true.
