Many economists already argue that the war on poverty is more like war on poor, and that giving housing to the homeless and unconditional income to the poor actually saves a lot more than putting them on welfare with a view to eventually getting them into workforce. Because of extenuating circumstances too complex to be simply explained succinctly, many people could not find jobs as easily and going on the job market for so long and while under welfare puts more financial and mental strain on those individuals. It costs more to put people on welfare, as you have bureaucracies to pay as well, than to simply give the poor unconditional cash transfers and housing. We're also in an increasingly automated world where jobs are becoming less common so universal basic income is a must.
