There are a number of tasks like rebuilding infrastructure that most people agree is necessary. There is some set P of people that would be willing to do this in exchange for a $24k salary. There is also a subset S of people (of set P) who would be willing to volunteer to do these tasks (for "free") assuming they receive $24k a year from UBI. If the subset S is almost equal to P, the government should be able to start a large scale volunteer program that would be structured like the WPA. If the subset S is much smaller than P, the government cannot do this. Do we know what the size of S is compared to P?
