Catalan are not fighting 1v1 some other region, they are 1 v rest. Even if every other region is less politically powerful, their sum is more powerful, and their sum benefits from extracting economic output from Catalan. Catalan cannot reasonably get a constitutional change because the rest of the regions benefit from them being part of Spain. Again, it's a one vs rest ordeal.

Welcome to reality mate. You cannot get a constitutional change if you burned your political capital decades ago. FFS, even the Basques turned their back to catalan politicians.
