Catalonia sends much more money to the central government than it receives (the difference is an amount equivalent to 8% of the region's GDP, according to a Guardian article that's a few years old). I wonder why shaking off the central government wouldn't be a win for them financially, even if they spend more than they ought to.

This is only a part of the entire equation. Politics could be happy and sell their triumph for a while, but entrepreneurs an companies at this point would had a big problem and probably not so happy

Yeah, I think this whole secession thing is a bad idea since the less tangible parts of breaking up a functioning country are so awful. It's pretty much always a better idea to fix things if it is possible.

So I say advisedly that if the attitude and misunderstanding of facts among some of the unionists here is representative of a larger whole, it might not be possible to fix things. That's an outsider's point of view.
