I always assumed that any money you earn would then be deducted from future payments Not directly, at least not in most described implementations. Most implementations say that, if you qualify, you get 1000€/month every month no matter how much you earn. Now a lot of people add a secondary mechanism where some or all of that money gets clawed back, indirectly via increased income tax, if you earn 'too much', but the base idea is the 1000€ gets deposited into your account every month no matter how much or little you earn. The rationale for this is a), not do disincentivize doing extra work and b) to simplify the system as much as possible and remove the need to spend a lot of extra time and effort on means testing, fraud detection, handling complaints etc.
