Wall Street Journal:

Charles Munger, vice chairman of Berkshire Hathaway, the other day described Silicon Valley billionaire Elon Musk as a “genius.” Maybe he was alluding to the Tesla CEO’s cunning ploy to mine subsidies from Nevada taxpayers.
 Last week the Silver State’s legislature unanimously approved $1.3 billion in tax breaks for Tesla to build a $5 billion lithium battery factory in Reno that will supply its electric-car plant in Fremont, California. “We have changed the trajectory of this state, perhaps forever,” declared Republican Gov. Brian Sandoval, who wagers that the “Gigafactory” will grow the state’s economy by $100 billion, or about 80%, over 20 years. Will he take that bet to Vegas?
 Politicians bribing businesses to locate in their state is an old if unfortunate story. Tennessee this year offered Volkswagen $274 million to expand its Chattanooga plant. Last year Washington awarded long-time employer Boeing $8.7 billion over 16 years to build its new 777X jetliner in Puget Sound.
 But the Tesla giveaway is in a category of its own, coming in an unproven market for a company that has never recorded an annual profit (based on generally accepted accounting principles), notwithstanding various subsidies. Nevada’s gift is 15 times larger than any incentive package the state has awarded and among the richest nationwide.
