i mean not to shit on eu or anything, but a lot of people used it as a stepping stone to escape to the us afterwards. what you're describing would only apply to low-skill low-ambition workers who only wanted to save enough money to build a house back in your home country and return after they pay it off. i mean, great: you still need money to pay for maintenance, utilities, food, if you have a car, then car purchase, fuel, maintenance etc etc.
