Presidents Donald Trump and Xi Jinping have backed away from the escalating U.S.-China trade war by agreeing to restart negotiations between their two countries at the G20 summit. Trump held off additional tariffs on Chinese goods and Xi agreed to buy more U.S. agricultural products. No formal joint statement spelling out the details of how the negotiations will move forward was provided, and given the rocky history of past negotiations, the future path of trade policy between the two countries remains in a fog. This uncertainty, as well as uncertainty with America's other trading partners, is a nightmare that has not yet ended for businesses engaged in international trade.

Bernie Sanders’s ignorance of economics and history seem to know no bounds. The latest? On June 18, the font of wet-lipped wisdom decided to continue his stellar track record of pushing for the opposite of what markets and economic growth need by Tweeting: "The video game industry made $43 billion in revenue last year.

Even some free-market economists, such as Duke University’s Michael Munger, argue for a UBI that would replace the current welfare state.
