Rule that the hurricane- affected Caribbean islands should tax their offshore- accounts to pay for (some ) rebuilding of the destruction.
Why is this important?
It will continue the movement against tax-havens which promote inequality and tax-evasion. It is hypocritical that these islands deprive other countries of tax-revenues and then immediately turn to the same countries to bail them out of a natural disaster. Hopefully if these islands are spending their own money, they will employ locals rather than importing expensive outside "consultants/experts".
