In this context, “Michael” in Ireland raised a pertinent question:
“Do you think that it is possible (technically) for governments to tap into the trillions which are hidden offshore?”
To which the answer is: yes, plenty of it. There’s some $8-35 trillion or so sitting offshore, depending on how broadly this is measured, which can certainly be tapped with stronger political will. And we must never forget that while all countries are victims of offshore chicanery, lower-income countries are the worst hit, as dictators and oligarchs loot national treasuries and sew up their economies into private fiefdoms, then transfer their ill-gotten gains overseas and stash it offshore.
Greater transparency would mean that the dictators would know where their own subjects have hidden the stuff so it can be nicked, right?
