  Updated on November 5, 2023                                                         * John has prospected for gold in Arizona 10 years. His experience taught him to deal with the terrain, heat, and gold fever. He makes tools. The sheer size of the mission with its white stucco makes it a grand sight from a distance (The White Dove of the Desert). Lost Silver Mines Some of the fondest recollections of my youth are trips from Tucson, AZ, to Nogales, AZ, when out-of-town visitors arrived. My sister and I would choose which of the broken crayons we would each take for the ride. We would very carefully fill a Band-Aid metal tin with all of the fractured crayons we would need to color our drawings as we traveled south down the highway. There were rocky mountains full of old mines, mostly silver, and mesquite-speckled verdant hills on either si...

  Updated on July 13, 2024 John is a retired math teacher who is involved in many activities. He writes, builds model ships, gardens, reads, and prospects for gold. A Mysterious Beginning As early as the 18th century, uranium was known for emitting green and yellow hues. When mixed with glass, its fluorescent effects are quite striking. Dating to 79 AD, uranium oxide (what you get after the milling and processing of uranium ore) has been found in some Italian glass. Of course, its chemical properties were not known. Today, uranium plays a huge role in our national economy, and a significant role in Arizona's economy. HEUraniumC, A billet of highly enriched uranium that was recovered from scrap processed at the Y-12 National Security Complex Plant.  Carrizo Mountains Uranium mining has taken place in Arizona ever since 1918. Before the uranium boom in the 1940s, uranium was basically a by-product gotten as a result of vanadium mining and mining of the mineral called camotite. D...

Why Millennials May Soon Face the Same Wealth Blame Once Aimed at Baby Boomers

Image
 Here is the basic question to be answered: It seems to me that those who blame baby boomers for causing economic problems due to a concentration of wealth (implying greed) are actually blaming the size of the cohort. Is there an argument that the same criticism, by the general population, will fall on millennials? The response - The criticism often directed at baby boomers for concentrating wealth is usually framed as a moral failing, but the underlying cause is structural: boomers entered adulthood during unusually favorable economic conditions, and their large cohort size made their gains highly visible. Today, baby boomers hold between $78 and $85 trillion in household wealth, amounting to roughly 51% of all U.S. wealth despite representing only about 20% of the population . Much of this accumulation came from timing rather than greed. Boomers bought homes when national home prices were roughly 3× median income , compared with the 5.5× income ratio millennials face. They att...
