All good points. Don't forget that back then more people were agrarian based than now. We have 95% of the population that could not farm or hunt for anything to sustain their families. Back then, people were more self sufficient than now.
Today, we would be killing one another to take what our neighbors have. We don't hunt, fish, or farm. We gave that up for 7-eleven and Food Lion. I doubt inner city Gangtas will take canning classes.
Most of our large metro areas are loaded with dependant citizens. Shut down trucking and our stores would be empty in hours. Destroy our economy and we have no way of sustaining those heavily DIMoRAT metro areas. Liberals would starve in the millions.
