I am in favor of self-sufficiency, BTW, and only wanted to introduce a little humor. And stock up on food to save money against inflation ahead. Find ways to lower your energy costs (heating, cooling, etc.—very important). Get out of debt any way that you can. Do those things by being frugal and becoming more technically educated. Looks like some rougher times ahead.
Don’t forget, though, that the maggots you want are the special, medical-grade, dung-free maggots.
Standard maggots, though will likely remain in bountiful supply.
