The mortared brick vs the mortgaged brick

We have finished making the bricks needed for the foundation of the dome. Today I timed myself, while I made the last batch of bricks. On my own, it took an hour to make 16 bricks. This is not factoring in the time taken to gather the materials, but the available materials are a byproduct of the excavation of the foundation ditch, which we had to do anyway. 16 bricks at $2.50 a brick in the store ( for this size and weight ) would have cost me $40. Sixteen mortgaged bricks, paid for over 30 years would have cost me $120 ! The equation I used is a simple one, using a calculator and third grade math. I multiplied by three. In other words, a house paid for over 30 years is about three times the cost of the same house purchased outright. That also means that it's triple the price for each component, down to the brick. So by making my own bricks with free raw materials and my own labor, in real time, technically I am making $40 an hour. However, I am saving $120 an hour, when compared to mortgaged bricks ! Not a bad wage. Today, I made 32 bricks over two hours ( 16 in the morning and 16 in the evening ). Compared to living in and paying for a mortgaged house, two hours of brick making is the same as a $240 payday. And I had many daylight hours left to do other things, such as visit with friends, meet a new neighbor, make a broom out of bunchgrass, play guitar, hound the used car dealership who still hasn’t sent me my title and registration after eight months and two citations, watch the scarlet colored sunset and emerging crescent moon, and write this journal entry. If I wanted to spend a full 8 hours of repetition making bricks, I would have been able to make 128 bricks, more than enough for the entire foundation...$960 saved. Making bricks is fun, especially with friends.
