Germany is a high-tech and heavily industrialized economy with a strong work ethic. Often described as the “engine of Europe,” Germany is the largest economy in the EU and the world’s fourth-largest economy overall. It’s also Europe’s most populous country. As a result, German passports bestow a high degree of travel freedom, though the tradeoff comes in the form of higher taxes than many of its European neighbors, though thankfully leaving the German tax system is relatively straightforward.
