They have always been. .
Not always Shakeel. During my long association in the Spanish property market during the nineteen eighties, tax was something other folks paid!
This was of course pre-EU entry and a hay day for investors and developers. There was no morality it was a gold rush. It had to change of course and it has. I would not advocate a return to those days but I do believe the pendulum has swung too far in the opposite direction. It will need to return to more moderate ground if the market is ever going to get off the floor.
In my experience the Spanish simply live for today in everything they do. It has nothing to do with tax avoidance, it’s simply their culture of consumerisim.
