Is independence good for Catalonia?

Nearly everyone thinks that we would like the independence of Catalonia. However, there are also disadvantatges. We must look at both sides of the question. 
It is true that there would be less debt to payand we wouldn't have to lay out money in the new country, because it would be another one. The country's economy would be better, but not everything is what politicians say. On the other hand the independence isn't always easy. One of the disadvantatges is that this fact woul mean separation from the European Union. That's why many citizens would leave Spain, but of course not only for that reason. 
Another one is that a lot of factories that we can find in Catalonia could leave. 
On balance, we should consider it. It can be benefit or not, because both, good or bad, a lot of things wouls change.
