I would dispute this. How many of the younger generation (not all, just using a generalized descriptor), can function without an ATM card, or be able to deal with empty shelves at the grocery stores.
How many know how to start a fire, build a shelter, have cooked over a camp fire, or open flame of any type.
Some of us who are older grew up with box fans in the windows… and maybe a window unit A/C. We had no A/C in the cars… My first 6 vehicles did not have A/C, and one was bought new.
Medical conditions, and insulin or other issues, while perhaps connected more to older people, do effect a considerable amount of young people. There are a large number of elderly that are not that dependent, though I would admit that there are a lot that are dependent, and it depends on what you call older. 45 up? 50 up? 40 up?
Also, there are those who are older who know herbs and natural remedies that can take the place of pharmaceuticals.
Back to your dependency on electricity, the young have rarely had to do without, while the older grew up without much of the ‘luxuries’ that seem so common today.
True, the older tends to have more medical issues that may require electricity, but you must consider, there are a lot of older people, and no all are dependent on oxygen machines…
After watching a rally in Georgia, it had old, young, white, black, Asian, Hispanic, and even had a Democrat politician, Vernon Jones… all supporting Trump and the Constitution.
You might find, there are a wide swath of society that is on one side, and it seems they are angry at both the Democrats and many of the Republicans. You may want to reevaluate.
