I grew up with the idea of Victory Gardens by way of my great grandmother. She taught me that gardening was good for America and the patriotic thing to do because it freed up resources for WWII.
Unfortunately WIN gardens will help the grower but few if any companies still hold to the laws of supply and demand and their costs will remain high if not rise even more. My electric company is a perfect example. They recently got approval to raise rates to make up for “lost” revenue due to falling consumer demand.
Supply and demand always applies. It’s human nature. Its effects are not always obvious, or immediate. Government protected monopolies pervert supply and demand, but they don’t repeal it. Over time, people will find alternative products or services, if pricing is out of line with the intersection of supply and demand. DirecTV and Dish network were the answers to cable tv, which have local monopolies.
