I'd think twice about living in Catalunia
Currently living in Spain and while I have certain understanding for self-determination feelings, I come from a country with strong regional differences (arguable a lot stronger than the spanish - catalan ones) and I'm flatly opposed to nationalist movements in my country of origin too.
The reality is that Spanish government is certainly flawed, but Catalan government makes it look good in comparison.
The Catalan region is paying in more into Spain than it gets out, but no shit Sherlock, it's the richest area in Spain, that's how things work where you at least attempt to serve the common good.
But it's an easy distraction from the fact that the richest area of Spain seems to be unable to balance its books. Easier to blame central government "stealing your wealth" rather than getting your own house in order.
