There are many types of job where market forces cannot solve the problem. (Within the context of the Universal Basic Income) there may entire categories of types of job that could be created to solve social (in the most general sense) or civic problems. For example charitable or education related activities are low to no profit - or at least it is not easy to measure their benefit directly or immediately, but high social value in the sense that they mitigate future problem that result in increase expenditures or taxes and so have long term value. Since the market uses money and direct profit as a means to measure everything it simply cannot deal with this.
