I hope things continue to go well for you and you feel little pain from the coming economic downturn. But I think the main concern for average families with well maintained family finances is that their jobs will be disrupted. Even though you appear relatively safe, your company may not be and your neighbors may not be.
Many things are interconnected in our economy. Suppose your company can't get a loan to purchase inventory, or suppose your company's major customer(s) can't get loans to do business, or maybe the major supplier(s) for your company. Any of those things could adversely affect your company and your employment.
Suppose most of your neighbors lose their jobs and start knocking on your door for food, or maybe they will simply lose their homes and move away leaving your neighborhood full of unoccupied dwellings which drive down the value of your own home.
Some people will remain relatively unscathed through this, but most people will feel some pinch through their connection to others and through the companies they work for.
