Guillotines are for after the masses have already stormed the present day equivalent of the Bastille and are in power.
When the shit finally does hit the fan, (after the food shortage and the resulting horrific riots) the average ‘citizen in revolt’ will use whatever weapons are at hand to go after their oppressors and their enablers.
Please lets not forget that federal contractors will get nothing, and at least here in the DC area, TONS of non-federal employess will be affected. Ridership is WAY down on the Metro System, and practically no one is buying lunches downtown. The Smithsonian Museums and the National Gallery, the Botanic Gardens, etc. are all closed so there are no tourist dollars either. The food trucks and small businesses are all getting hit with bills for their rent etc and with no end in sight, they could go out of business. Uber drivers and Lyft drivers are complaining that there’s far fewer rides, AND more unemployed feds driving for Uber and Lyft, so it’s even harder to find a fare. It would be good news if there were only 800,000 families affected, but in fact the number is far, far higher than that. Beyond my ability to estimate at any rate.
