Something similar happens in Romania, with basically all of the poorest counties (județe) and their hometowns (municipii) in the hands of the Social Democrats. They are Social Democrats only with their name, as they love to embezzle public money instead of investing into schools, hospitals, infrastructure, and the people that are paid well are only those that are vital for them to get support. Otherwise, too little private investment exists in those places. And when things are done, the quality of the works is poor (e.g. asphalt poured straight on dirt that you can rip with your bare hand etc.)
