One of the most obvious beneficiaries of the trend will be the restaurant industry. However not everyone has been benefitting in the current business climate. As an article in yesterday's New York Times pointed out, most of the gains in corporate America have been made by firms that cater to higher-end customers. That's because the government's asset purchasing has swelled the purchasing power of the upper-classes whose stock and real estate portfolios yielded big returns in 2013, which is why high-end retailers like Barney's are edging out companies that cater to the middle class like J.C Penney (JCP) or Loehmanns. The same trends have been playing out in the restaurant sector. One of the largest diversified restaurant chains in the country, Darden's (DRI) has seen sales in its upscale locations swell, while sales at many of its biggest brands, like Olive Garden and Red Lobster, have stayed flat. Hedge fund activists and investors have since started pressuring the company's management, to spin-off its higher-end brands into a different company.
