Good job for all those involved in exposing these people. Now that they ARE exposed, what measures can actually be taken to get justice? No lawsuits would be successful, as no courts would find them guilty. These people ARE the justice system.
No government officials can help solve the problem identified in these Paradise Papers, because these people ARE the government.
What makes these people so rich and powerful is one thing --- private ledgers!
They control the ledgers, so they control everything recorded in those ledgers, including financial data.
But, there is a way justice is being achieved, via the blockchain. The blockchain, by its very nature takes ledger control away from the rich and powerful.
In the wake of the blockchain as a distributed, open source ledger, these people will one day not be able to punish people by refusing to approve and record transactions and everything else. Without that ledger control, whole populations of people will have more control of the value of their work and products, and subsequent payment.
With this business and economic structure, the Paradise Papers Participants will lose; therefore justice will be served.
