America Inc is hoping for a tax bonanza. It may be disappointed

Corporate America has at least one big thing to celebrate about the presidential election: it has erased the possibility of a rise in the country’s corporate-tax rate, as had been proposed by Democrats. Weighed against the cost of tariffs—and more abstract concerns about the health of America’s institutions—the promise of lower taxes and deregulation warmed bosses to Donald Trump during the campaign. Shareholders, who stand to benefit directly, rejoiced at Mr Trump’s victory, sending the S&P 500 index of American stocks to a record high.
