works both ways but certainly works.
My wife (from Manchester) studied in Scotland then also did a year in Paris and New York thanks to scholarships. If you're bright enough the world is your oyster, as long as you get noticed early on. Her way wasn't entirely paid but with some part time work she didn't have to take on any additional debt. That's all without any help financially from her family.
Being fluent in even one additional language can absolutely open doors for you, I wish I'd paid more attention at school now..
