Concerning the people who have moved to Bologna from foreign countries, it is possible to individuate two macro areas of origin--Eastern Europe (Romania, Moldova, Ukraine, Albania, Poland) and Asia (Bangladesh, Philippines, Pakistan, China). Although the main reason to move to Italy is work-related, it is still difficult for many Italians to process such diversification of the population and the emergence of new needs. Apart from the fact that some popular political parties invite people to despise other cultures, it is also a matter of social inclusion in each person's everyday life.
Piazzola is center stage for the variety of economic, demographic and cultural change related to immigration. Many of the Italians that used to work at the market left their job due to high taxes and the economic crisis. They were replaced by foreigners who didn't have problems working in difficult conditions. As a result, some "Bolognese" -- that is, multiple generation Bolognese-- avoid shopping there because they fear it has become less authentic than before. Some complain about the noise, the quality of the clothes or the new types of objects sold.
