Why is the that the threat of abject poverty the only way to motivate poor/middle-class people, while pre-gifting tax cuts seems to be the only way to motivate rich people? for too many people right now it isn't worth it to work (Too little difference between working wage and welfare) That is complete nonsense, peddled by the current government and their think tank lapdogs (including CEPOS). They've only ever been able to find a few persons here and there who even barely fit their bogeyman of a deliberately workshy person, while the vast majority of unemployed people would love to have a job. CEPOS et al. also tend to include people with severely limited ability to work in their grouping of "lazy" workshy people.
