Italy, autonomies, Lega Nord, politics, investments, long
Actually we have had a similar dynamic in #Italy: most of industrial investments have been in the northern part of the country with the centre and (much more) the southern Italy left behind (under the control of Mafia, 'Ndrangheta and other criminal organizations).
For decades we have had a political party (#LegaNord) that pretended to fight to get independence of the northern Italy, with an hate rhetoric directed at southern people.
Now it evolved to the #Lega which directed the #hate towards immigrants (poor ones, obviously... just poor ones..) but left any separatism and independentism behind.
Their actual selling point was: we are riches and our taxes are going to support people (and bureaucracies) who live at the south. Which technically was actually true, but even fair since, we are all Italians after all.
Our history teach that when a Nation builds a rich region hoping that it will drive up all the national economy, it will at the same time mining its own root.
The rich cannot really feel #solidarity.

NOTE: I don't know if it's the same with #Spain and its autonomies.
Thank you both for your perspectives.
