I wonder what 'civilization' will look like when it all collapses. It will collapse because neither party will do what is needed to change direction. They are only arguing about when we go over the cliff instead of changing directions. Dems pedal to the metal. GOP an inconsequential rate slower.
When it collapsed in Germany in the 30s, they got Hitler. Scarcity returns humanity to the wild. Could get ugly. Teach your young kids how to use weapons, do some subsistence farming, and know how to maintain equipment like small engines. If nothing else, it will give them some hobbies some day.
