It takes, I think, a good number of semi-truckloads of food per day to keep New York alive. How long does one think it will take, once the scam infuriates those in 'flyover country', to have those shipments stop?
Sounds a bit like the final chapters of 'Atlas Shrugged', which is how this silly law would likely play out in the long term.
Or, let the cities get the Mexican-trucked food from Central America until it sickens them all.
