Most of us should probably quit our jobs, sell our homes and most of the useless things we own, buy a fifth wheel, bind and gag our spouse, throw them in the truck and move out into the nowhere lands.
The problem for most, is you still have to pay the bills. You still have livestock that needs vetting, health issues that need doctoring and most people do not have the skills or physical ability to repair everything in a home themselves. Family members; children, grandchildren have similar issues.
Some do not have spouses that are nearly as convinced that the shumer is about to hit the fan, do you divorce your spouse? Or find a way to do the best you can? Everyone has a line as to what sacrifices they are willing to make.
Everyone’s ability to prep, and their situation is a little different. I don’t think it means necessarily that they aren’t serious. They probably wish they could do more but, get defensive because they can't.
