Salary Guide for Software Developers in Barcelona

If these salaries are accurate it is a sad prospect for developers coming from other cities like London or Berlin to Barcelona. Salaries in London are three or four times higher than there. Sure the city is becoming a startup hub, but can they maintain these low salaries for long?, will investors keep funding startups in Barcelona if salaries go high? Or is it all just a bubble, like famous and longtime spanish investor Luis Martin Cabiedes says?

Spain it's always been a hostile place for entrepeneurship, hope it changes soon.
