The main reason for the Britain joining the EU was reduction of trade restrictions between members. Most Brit folks didn't feel the necessity to move anywhere since they had enough and more *resources.Well, that’s kinda the point of the EU. British Expats could move to Spain freely without speaking a lick of Spanish, move to Germany, Sweden, the Netherlands or wherever you wanted and being able to start a life in there without going through an immigration process.
Most people I know benefit from this, the only complaints I’ve heard come from non-EU people because they feel left out.
Not having to pay international tuition and being able to work without restrictions as a student’s it’s a game changer: they study, learn the language and work at the same time.
(*we all know how they made it hehe )
