One of the reasons why it was rejected, is because the supporters were slightly too idealistic. The elephant in the room is obviously, who would be eligible for the BI.<p>Most of the supporters and some of the initiators of the initiative, that I've spoken with, were strongly for a idealistic implementation, meaning everybody physically located in Switzerland would be eligible.
While the number one argument against a BI was that exactly this absolute unconditionality would be a recipe for a disaster, especially given the current migration situation in the EU.<p>The Swiss are notoriously risk averse, so any proposal that does not take into account any possible side effects, usually gets rejected with a margin just like this one.<p>To have a realistic chance of acceptance, I think the 'unconditional' needs to be dropped. Add a conditional on citizenship, flesh out the financing some more and just try again. The problem here is that a "national basic income" instantly catapults you politically very far right, even though it's a very leftist position.
