In recent weeks tens of thousands of protesters have taken to the streets in Spain’s most popular tourist destinations. From Málaga to Mallorca, Gran Canaria to Granada, locals are revolting against what they see as the hollowing out of their communities with the buying up of properties to turn them into short-stay holiday lets for people they argue don’t respect their locality, culture or language. UNESCO has described the situation as "totally out of balance".

On one level this is an argument about economics, but the implications are profoundly moral. People shouldn’t feel like second-class citizens in their own towns, but we also recognise the freedom to move, rest and discover. The affordability of travel makes mass tourism possible, but it’s lamented by those who see it as selfish, narcissistic and damaging to native cultures and the environment. And yet travel supposedly broadens the mind and the soul – a cultural exchange that can be a catalyst for self-improvement, make us more empathetic, and provide a livelihood for host communities.

Should foreign tourism be discouraged? Or if it’s mass tourism we’re worried about, what can we do about it without holidays becoming an elitist pursuit?
