First off, forcing punishment when an actual beneficial solution better accomplishes a goal is the definition of stupidity and pig headedness. Are you listening Donald Trump?
If a country is inflating their prices on their exports to us then they must cut their prices to match our competitive price for the same commodities…and then cut their price an additional 50% they will be eligible to receive the rebate of that 50% of price back to them by our central bank.
And while their at it they would be smart to implement the 50% Discount/Rebate at retail sale in their own country because it doubles their population’s purchasing power and thus demand for all of their commercial agent’s goods and services thus supercharging their domestic economy.
The combination of the excellent tool of double entry bookkeeping and a new and innovative applied concept/paradigm has historically resolved previously seemingly unresolvable problems.
Play out the effects of the policy until you see how evolutionary this single policy is.
