Vueling First officers usually go to eat at Mac Donalds anyway plus they share a basic flat with 3 or 4 other mates. Being at Barcelona, Madrid, Roma or wherever, who cares? the cost of living will always be high for them.
Back 15-20 years ago, I would say that 95% of them would NOT pass the first stage of Iberia's pilot selection, due to lack of skills, experience and knowledge, nowadays if you pay for an A320 type rating and accept a ridiculous 6 months contract with an unstable roster, 12 hours of duty per days, a bad base and a salary equal to what what earns an Iberia air hostess, you CAN indeed be a pilot!
At least the CEO can buy his wife a nice car and eat everyday in great restaurants.
