If you've read the news recently, you'd know that in many parts of Spain, tourists are being harassed because the locals have grown tired of the endless masses of people being shipped in. In essence it's a signal to the local government that the issue is not properly managed and that the locals will seek means to push their hand if they don't address it themselves. There are numerous examples of problems, from traffic congestion, low to no living space availability, etc. So in that sense, the question raised by this comment thread is very relevant and indeed something everyone should check these days before travelling — it doesn't matter if you're going to a developed country, you might not be welcome.
