How about looking at modern history? We are being told today that Global Warming is going to be the death of us but in the mid 70's the "scientific community" was forecasting an imminent ice age. Recent EPA edicts are mandating the cessation of coal-fired power plants. Never mind that we have the cleanest coal burning facilities in the world and are now selling our coal to China and India where they don't even have emission controls. How does that help "Global Warming"? Meanwhile, the best estimates are that electric energy will cost from 2 to 3 times as much in 10 years!
In the 70's a new theory was proven that most of the capacity for learning and brain development is established from gestation to 5 years of age. This led to the development of the WIC program. The government created a wonderful way to provide much needed nutrition to poverty level women, infants, and children. Specific foods were selected for their high nutritional value and distributed through Health Boards or in rural areas sometimes by the milk route drivers. Just last week a news release from Washington University in St. Louis stated that new research has shown that an astounding 22 percent of U.S. children live in poverty, which can have long-lasting negative consequences on brain development. A child psychiatrist there has suggested that it must become our top public health priority. Well duh! We not only knew that 45 years ago, we implemented a fix for the problem. You can even apply for assistance online.
In 2000, Chris Wallace, then with ABC, reported on a 20/20 segment that Planned Parenthood was selling aborted fetuses. A hidden camera revealed a thriving industry where aborted fetuses, which women donated, were being marketed for thousands of dollars. The Doctor being secretly recorded was eating lobster bisque and roast duck while explaining the sale of fetuses for their parts. Sound strangely familiar? Even the bad guys don't learn from their mistakes.
I told my grandkids that if we don't have enough time in school to learn the really important stuff, maybe we should look at going year round. Now that was a mistake that I learned from!
