Italy became a nation-state in 1861 when the regional states of the peninsula, along with Sardinia and Sicily, were united under King Victor Emmanuel II. Italy has a diversified industrial economy with roughly the same total and per capita output as France and the UK. This capitalistic economy remains divided into a developed industrial north, dominated by private companies, and a less-developed, welfare-dependent, agricultural south, with 20% unemployment. Most raw materials needed by industry and more than 75% of energy requirements are imported. Tourism is very important to the Italian economy: with over 37 million tourists a year, Italy is ranked as the fifth major tourist destination in the world. The current government has enacted numerous short-term reforms aimed at improving competitiveness and long-term growth. Italy has moved slowly, however, on implementing needed structural reforms, such as lightening the high tax burden and overhauling Italy's rigid labor market and over-generous pension system, because of the current economic slowdown and opposition from labor unions. But the leadership faces a severe economic constraint: the budget deficit has breached the 3% EU ceiling. The economy experienced low growth in 2006, and unemployment remained at a high level.
