At least in Germany, the answer is nuanced: https://www.bmi.bund.de/EN/topics/migration/law-on-foreigners/freedom-of-movement/freedom-of-movement-node.html https://www.bmi.bund.de/EN/topics/migration/law-on-foreigner... you are apparently not allowed to just move there if you aren’t self-sufficient: > EU citizens have the right of residence for longer than three months if they - are workers or self-employed persons in the host Member State or are seeking employment (for a certain length of time); - are not in employment or are students or trainees and have sufficient resources and comprehensive health insurance cover; - have the right of permanent residence (following legal residence of five years). - Family members, regardless of their citizenship, accompanying or joining an EU citizen who satisfies these conditions also have the right of residence for more than three months. > So the underlying idea is that in order to reside for more than three months in another Member State, EU citizens must have sufficient resources for themselves and their family members not to become a burden on the social assistance system of the host Member State.
