Even if it wouldn’t reduce people's willingness to work (which the article doesn’t prove in any way), people would work on whatever they feel like, not on what our society needs. Because in the job market, wage signals work like price signals in other markets: they incentivize people to move in the direction most valued by the economy. Like IT right now. So we may be doomed to a society of grasshoppers with nobody willing to be the ant - like in the old fable.
