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?
Implement the 50% Discount/Rebate policy at the various points of retail sale in the economy thus doubling the purchasing power of every one of your citizens, super charging the entire economy and making investment in actually productive facilities in the country, which we foolishly exported, much more attractive.
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 and beneficial it is.
