how you can compare the situation in the UK with Spain baffles me.
The stories you highlight, yes, show some problems in the Uk. However, as those stories show, the authorities have taken action, people have been arrested & charged, trials have taken place & penalties imposed.
You chose to highlight a story about the police looking at thousands of investors in the UK who may have have lost millions. Well, are the Spanish police looking into similar problems in Spain?
Will any prosecutions take place in Spain?
People can get conned anywhere in the World, a true test of a Countries legal system is what happens then. At least in the UK ‘some’ form of justice will happen. People will go to prison. In Spain, not a chance!
