With the modest size of the monthly checks, most of them may need to do that anyway.

But the obvious point is to help "artists" in Ireland. It's pretty normal for small nations to want to cultivate / protect / subsidize their arts / culture / language / whatever. The Irish gov't isn't trumpeting this program because they think it'll annoy Irish voters.

artists dont do "normal" and generaly experience reality from a particular, and personal point of view, and grocerie store managers and young artists will almost certainly have mutualy antagonistic points of view. artists thrive in random spontainious environments, but forget about food, so we give them money, that they give to normal grocery store clerks, and we all forgo the seething frustration that would result from your suggestion.
