As in Tower of Babel engineering firm and Crematorium?
Now everybody knows you have a limit on the number of words that can be 'written to you' at any given time. If you don't like people picking on your goat don't show them where you keep it. 11teen was the magic number in my world. Like on the 11teenth day lists were created. Easy to do, make something perfect and then tighten it all just a little bit more. Murphy can explain the rest of how that goes.
The homeless should be given homesteader permits at a suitable location. (full in 100 years time at a variable growth rate) Hudson Bay would be mining and fishing, industrial size rather than 'family farms', The Bay or the Great Lakes would be suitable. When LaFarge ran out of lime in a big mine on Van Is they cursed because the land became useless as it was pit-run they encountered. Pit-run on a bedrock exposed location means that material is laid down about 1 m deep and all the utility lines can be buried and the foundations can now have basements at no additional costs. They eventually wised up and that is the gravel that was used to twin the highway that runs past the place and now goes to the far north of the island.
As a welder you should have all sorts of ideas come to mind if you watched Bering Sea Gold as they are starting a new kind of mining that will start with the sediment washed out to sea. Once they get to where the river current and tides have washed away the sand they can start with that material. The props from the barge can be used with a suction hose to vacuum up huge amounts as the hose is big enough that the nozzle would have to be placed and moved with the boom of the how that is part of the barge already. Get some electronics involved and the boom could be computer controlled to keep the swivel head on the end of the boom in the same orientation to the bottom via a variety of ways from sonar to a ski that rides the bottom. Our role in the international trading might slow down but that doesn't mean the local situations have to be no employment and only breadlines. If Canada got plugged up[ with snow the whole of the east side of Canada would become refugees looking for a home. Brought up to show the solutions in that instance would be an open border support if you lived in the east.
