Firstly, I would like to talk about the current problems which are hitting Spain. However, the birth of this problem is localized in Catalonia. There are two parts involve in this situation: catalan people who wants to be independent from Spain; and the second one, catalan people who wants to remain in Spain.
Secondly, we don't have to forget the attack by the terrorists from ISIS, which caused several deaths and a lot of hurt people. This attack was provocated the last month in the center of Barcelona, in one of the most crowded streets of Europe, the second one concretely, called Passeig de Gracia.
The last but not least, the economic situation in Catalonia. A lot of companies like banks, industries, etc; are moving their main bases to another Spain city such as Madrid, Valencia, Alicante, etc. Due to the last two problems that I commented here before. It has caused an unbalance and uncertainty if we talk about legal safety and economy safety.
