A one-sided use of political labels

"As earnings sizzle, a chill for workers" (Dec. 18) was informative and, on balance, well written.

However, I found it curious that Tom Petruno felt compelled to instruct the reader that the Economic Policy Institute and the Center for Economic and Policy Research were liberal while remaining silent about the political orientation of the Business Roundtable and the Brookings Institution.
