I’m left handed, which means I’ve spent my entire life fumbling with scissors, wiping ink smudges from my pinky finger, and thumbing through magazines backwards. I’ve always accepted that being left handed comes with certain challenges, but there’s one thing about the condition that has always perplexed me: Why are we lefties so damn rare? It turns out, a plausible answer may be found in evolutionary theory. After googling a number of left-handed factoids in anticipation of International Left-Handers Day, which is today, I stumbled across a fascinating TED-Ed lesson from Daniel M. Abrams, which adeptly breaks down a mathematical explanation for why the rate of left-handed people has remained steady—about 10% of the population—for the last 500,000 years. The reason boils down to two words, “competition” and “cooperation,” and how the balance between those forces plays out in human societies. Let’s start with … [Read more...] about Why is left-handedness so rare? It comes down to these 2 words
Why is kosher meat so expensive
Of the approximately 10,000 service stations in California, less than 15% are independent and not affiliated with a well-known brand. That means less competition than in many other states that have higher proportions of independents. What's more, in California, there are no independent refiners to supply independent retailers. As a result, the no-name stations have to buy their fuel from big refining companies that already have contracts with their branded stations. When supplies run short, the unbranded stations may have difficulty getting gasoline, which causes their prices to soar higher than those at branded stations. … [Read more...] about Why is California gasoline so expensive?
Amtrak has been operating since 1971, but it has yet to become profitable. With high ticket costs, Amtrak has become a less viable mode of transportation in the United States – it’s often more expensive to take a train than it is to fly. The US government attempted to make Amtrak financially self-sufficient with the Acela Express, but Amtrak still has a large sum of debt from years of underfunding. Following is a transcript of the video. Narrator: Amtrak is the only passenger railroad service that operates throughout the continental US. With about 500 destinations, the service has been operating since 1971. But with high ticket costs, Amtrak is becoming a less viable mode of transportation. In fact, it’s often more expensive to take an Amtrak train from New York City to Boston than to fly. Why does the US, a country that created billionaire railroad tycoons, have such an expensive and inefficient train system? Amtrak has had a long history of financial … [Read more...] about Amtrak has lost money every year since 1971 — here’s why train tickets are so expensive

ByNellie Bowles March 26, 2019 The wealthy of Silicon Valley ought to be living their very best lives right now. John Doerr, an early Amazon and Google investor, calls their moment “the greatest legal accumulation of wealth in history.” And yet, the people of Silicon Valley seem determined to make themselves miserable.

It is a question I get asked frequently, most recently by a colleague who was shocked to find that his new pair of prescription eyeglasses cost about $800. Why are these things so expensive? The answer: Because no one is doing anything to prevent a near-monopolistic, $100-billion industry from shamelessly abusing its market power. Prescription eyewear represents perhaps the single biggest mass-market consumer ripoff to be found. The Vision Council, an optical industry trade group, estimates that about three-quarters of U.S. adults use some sort of vision correction. About two-thirds of that number wear eyeglasses. The average cost of a pair of frames is $231, according to VSP, the leading provider of employer eye-care benefits. A pair of single-vision lenses averages about $112. Progressive, no-line lenses can run twice that amount. The true cost of a pair of acetate frames — three pieces of plastic and some bits of metal — is as low as $10, according to some estimates. … [Read more...] about Why are glasses so expensive?
