Earlier quoted context omitted.
My understanding is that basic income can only be "unconditional." If there are conditions attached to it, what might be they?
While that's how I read it, perhaps the condition would be citizenship. I.e. they don't want to simultaneously allow more people into their country and also give everyone in their country a lot of money for fairly obvious reasons. However, the article doesn't give translations of the actual measures so it's hard to say.
I'm probably running afoul of language/translation shear...
