Who Boycotts Wal-Mart?

Who Boycotts Wal-Mart? | National Review Online:
Social-justice warriors who are too enlightened to let their poor neighbors pay lower prices. 
...Ironically, the anti-Wal-Mart crusaders want to make life worse for people who are literally counting pennies as they shop for necessities. 
Study after study has shown that Wal-Mart has meaningfully reduced prices: 3.1 percent overall, by one estimate — with a whopping 9.1 percent cut to the price of groceries. 
That comes to about $2,300 a year per household, savings that accrue overwhelmingly to people of modest incomes, not to celebrity activists and Ivy League social-justice crusaders.

Ultimately, these campaigns are exercises in tribal affiliation. 
The Rolex tribe, and those who aspire to be aligned with it, signal their status by sneering at the Timex tribe — or by condescending to it as they purport to act on its behalf, as though poor people were too stupid to know where to find the best deal on a can of beans. 
Or call it the Trader Joe’s tribe vs. the Wal-Mart tribe, the Prius tribe vs. the F-150 tribe.
