I agree that full implementation of a basic income looks unlikely in the near future, and while changes will most likely be incremental, I don’t think we need to solely be focused on the near term. I would argue the best strategy is to have a robust long-term vision about the kind of society we want to have paired with concrete steps to fight for in the short term.
You could argue this is the strategy with basic income pilot programs. Instead of just fighting for the implementation of a basic income, pilots not only provide more potential data to support the argument in favour of it, but it also introduces more people to the policy to gain wider support. Some basic income advocates also support a universal child benefit as a way to create a universal payment that could later be expanded to more age brackets.
