This is a nice theory, a narrative that might be difficult to prove in practice, however.
On a more meta-level, though, people's political opinions influence their interpretation of statistics, so even if you did prove this ROI, cognitive disonance will fight you extremely hardly. Instead of trying to convince people who are against any form of wealth distribution, it's 1% as difficult to convice the people on the fence (of whom there are also 10x more) , those who are ok with some distribution, that this is a pretty effective replacement/complement for current services.
