Whatever the rate of price inflation is, we need to beat it to even preserve our purchasing power. That got into discussions of what the true rate if price inflation is, and that we can have personal rates of price inflation depending on what we buy. So to simply break even, our investments have to generate a nominal return of 2%, or 3%, or 5%, or 8%, depending on whose version you believe.
But why do we need to preserve our purchasing power? Because in our modern society, we need to buy all kinds of things just to live from one day to the next. Food, water, heat, rent/mortgage, gasoline, insurance... the list goes on. But there's another way: you neutralize the effect of inflation on your monetary expenses by eliminating as many of them as possible.
You can neutralize inflation in the price of eggs by raising chickens. Overcome electricity price inflation by generating it yourself. If the price of manual labor is rising, do your own painting, landscaping, etc. Rising prices of meat? Convert the cost of your next year's meat into the cost of ammunition and gasoline by going hunting. Convert the price of just about anything into a time cost by patiently trawling Craigslist's free section. Learn to sharpen your own knives, build your own furniture, and on and on.
This approach doesn't actually require that you calculate the rate of inflation for these things, and it has the benefit of making you a more capable, awesome person more in tune with the workings of the world all around you. Your investments become responsible for preserving the purchasing power for the expenses you can't get rid of (like property taxes), and funding your ability to learn new skills and acquire things that make you more independent, like tools, solar panels, and internet access. By rendering price inflation increasingly irrelevant to your life, you actually boost the real returns of your investments! And it also magnifies your ability to pay for the purchased luxuries you just can't live without.
Here's a totally extreme example:
- You own a mortgage-free house that was so well-designed and insulated that it heats and cools itself purely through passive solar irradiance and the thermal flywheel effect, or all supplementary heating needs can be met through self-generated electricity or burning wood grown on your property.
- You don't need homeowner's insurance because your house was designed and built in such a manner as to almost entirely eliminate the danger from all possible local hazards. Floods? Your house is built on concrete stilts. Wildfires or termites? Your house is made entirely of nonflammable materials. Earthquakes? Your house is made of earthbags and weighs 5,000 tons. Tornadoes? Your house is subterranean. High crime or unrest? Your house is a virtual fortress with two foot-thick walls and reinforced doors and windows.
- Your house catches and filters enough rainwater from the roof to provide all the water you need for yourself and your garden. All domestically-used graywater is harvested and re-used in the garden, and there is no blackwater because your poop is turned into compost by your composting toilet.
- Your garden and animals provide all the food you need, and your animals feed themselves from parts of your garden you don't eat.
- Your solar panels and wind turbines provide all the electricity you need and enough to sell back to the grid to pay your property taxes and the cost of internet access.
- You ride your bike for transportation.
- You live in a country with free universal health care like the UK.
- You send your children to public school.
- Anything that needs fixing you fix yourself using your skills, your power tools run from electricity you generate yourself, and repair parts that you acquire for free from Craigslist using your bicycle, or fabricate yourself from raw materials acquired in a similar manner.
- All electric lighting uses LEDs that will last for decades.
- When your electric system's batteries need replacing, you scavenge working ones from cars in the junkyard.
Besides the modernity, the other principal difference is that all the money you make from whatever job you feel like having goes right into your investment account, which eventually grows so large and produces so much income that you can purchase absolutely any modern convenience you want with cash because nothing else is eating away at the gains from your investments.
