I’ve written several times about the possibility of using an endowment-like investment structure to establish a universal basic income that can be started at a municipal level and scaled up based on feasibility. Haven’t received much feedback on the idea. I thought it to be a possible work-around to things like scalability, constitutionality, and/or the problems of funding that can be found in government spending.
With an endowment, people can be certain a specific portion of their money goes to a specific activity, and the costs would be far less burdensome than establishment of a government program. To me, philanthropy is the civic duty of anyone with the means, and is the greatest potential intersect of socialist ideology and capitalism.
Capitalism and socialism are not mutually exclusive.
