It's a pity Spain country side is becoming a vacuum.
It's not unique to Spain though... And neither surprising, tbh. Who in their right mind would even want to live without stable electricity, good waste management and all the other things you take for granted in even small villages ( There is literally nothing there besides some houses. That's enough to take a break on some holiday... But very few people would be willing to suffer through that long term
"Mod cons" aren't generally the problem. What's missing is people who want to be there.
