> Only one thing could possibly improve the travesty that is fintech: a per-transaction tax. Even a $.0001 tax per trasaction would buy universal college education and universal medical care, with plenty left over to replace all coal and oil-fired power with renewables and storage and replace the air fleet with hydrogen-powered craft.

That would only happen if fintech didn't change their behavior in response to such a tax. I do not find that to be a reasonable assumption.
