An argument I frequently hear (and generally buy into) against impact investing is that fungibility of investment money leads to unethical actors taking the extra wins created by impact investing. Hence, one should optimize for capital gains in 'investment' buckets and optimize for philanthropy in the 'doing good' bucket.
I'm concerned that this argument could then be applied to the money in my philanthropic bucket.
That is, does reducing my wealth by giving shift more capital gains onto non-altruistic actors? Put another way, in the long run under market economies, does philanthropy reduce the power of altruistic actors and increase the power of non-altruistic actors? If not, why?
Thanks for elaborating! That's very helpful to understand and certainly strengthens the case for giving now (in the sense of power/capital transfer to other altruists).
