“It doesn’t matter how many ordinary people die, we in the elite will hold firm to our fantasy plan.”
If it ever happens to the Oligarchs, the policy will change the next day.
IMHO you have to understand that as long as the current policy remains place none of its authors or supporters can be held responsible.
If (when?) the policy is officially reversed then all of the shady backroom deals come out and the plan’s authors and supporters will be revealed for what they are. And, possibly they will be held accountable if not by the government then by the average citizen in some very public and private ways.
Remember the French Terror (1783 - 1794) at the beginning of the French Revolution with 40,000 “legal” executions. That piece of history is never far from the individual and collective memories of French politicians.
