Many Berliners are sick of that sentence: it's the slogan the city has been using to market itself. Poor, but sexy! Arm aber sexy! 12 million tourists visit the capital every year, but many in Germany complain about the capital: which is considered a black hole for investment. Because Berlin is 60 billion euros in debt. In every other country in Europe, people in the capital earn more than in other cities. Not so in Berlin. Still, the city is growing rapidly. Every year, over 40,000 people, especially foreigners move to Berlin.
