Here's one counter argument for UBI. Who will do all the boring work needed for building a dam / apartment ? If we are honest about it, most of this boring, physically harmful and repetitive infrastructure work is only done by the working class that chooses to do it because the alternative is begging. It's because of the threat of extreme poverty and unemployment that the working class works. If they are able to sustain themselves with UBI why would they work ?

Who will do the boring data entry work in our industry ?
