In this country, all children are supposed to have a shot at success — a chance to jump "from rags to riches" in one generation.
Even if riches remain out of reach, then the belief has been that every hard-working American should be able to go from poverty to the middle class.
On Tuesday, a book and a separate study are being released — both turning up evidence that the one-generation leap is getting harder to accomplish in an economy so tied to education, technological know-how and networking.
The three major credit rating agencies reached an agreement with New York Attorney General Eric Schneiderman on Monday to change the way they handle errors on credit reports. Under the reforms, consumers can initiate a formal dispute to challenge inaccurate information and agencies must use trained employees to investigate the complaints.
Wisconsin Gov. Scott Walker signed a right-to-work measure Monday that makes his state the 25th in the nation with such a law. That effectively means that mandatory union membership and dues are banned at privately owned businesses — a move strongly opposed by unions, which say it restricts collective bargaining.
The cheapest one will cost $349 and prices go all the way up to $10,000 for one that is gold plated. For that, Apple CEO Tim Cook said Monday, you can use your Apple Watch to make calls and send emails, check your heart rate and your Twitter feed and, yes, tell time, as well.
Apple, of course, has never been shy about touting its products, and Cook, at an event in San Francisco to announce the launch of the much-anticipated watch, called the device "the most advanced timepiece ever created."
When it comes to the current controversy over antibiotic use on farm animals, milk is in a special category.
Lactating cows, unlike hogs, cattle or chickens that are raised for their meat, don't receive antibiotics unless they are actually sick. That's because drug residues immediately appear in the cow's milk — a violation of food safety rules.
Milk shipments are tested for six of the most widely used antibiotics, and any truckload that tests positive is rejected. So when cows are treated, farmers discard their milk for several days until the residues disappear.
I had a lot of experiences this past week: I shot birds out of the sky with my eyes, my fingers were on fire, I flew on top of a drone over the arctic and looked into the jaws of a dragon.
I did all this without leaving San Francisco, at the 2015 Game Developers Conference, where the people who make the video games we love to play come to the city by the thousands to check out the latest hardware and software for making games.
