I read this as Soros endorsing the elite campaign against 'over- heating', which is to say for low growth. Inflation is a bit of a red herring and the fulminations against it coming mostly from central banks are a cover for high interest, low-growth policies favoured by ruling elites in the West.
(Incidentally, 'Global overproduction' is a myth, too. As long as human wants remain unsatisfied, it is ridiculous to talk of 'overproduction' in absolute terms. It can only mean overproduction relative to the restricted consumption fund set by the markets) -- Jim heartfield
