How about Canadian examples.

BC has cut taxes and delivered a series of balanced budgets to lead the country economically under the BC Liberals (actually a misnomer as they are Conservatives economically).

The Harper government according to the Parliamentary Budget Office delivered tax cuts mostly to the middle and low class income earners while handling the recession. Canadians saved more than $30 billion in federal taxes due to tax changes introduced under Harper according to the PBO. "Revenue and Distribution Analysis of Federal Tax Changes" May 27, 2014.

A massive New York Times research project report on the middle class released in late April 2014 found that the American middle class, long the most affluent in the world, has lost that distinction... to Canada. After-tax middle-class incomes in Canada — substantially behind in 2000 — passed the United States. Median income in Canada pulled into a tie with median United States income in 2010 and has surpassed it since then.
