Forbes on Costco v. Wallmart

Yes, Forbes, not some liberal media outlet, has this to say about why Costco is doing so much better than Walmart. Costco's sales growth is 8% compared to Wallmart's 1.2%. Why?

"Here’s a crazy thought—might it have something to do with the fact that Costco pays nearly all of its employees a decent living (well in excess of the minimum wage) while Wal-Mart continues to pay its workers as if their employees don’t actually need to eat more than once a week, live in an enclosed space and, on occasion, take their kids to see a doctor?"

So how does Walmart respond? By cutting its employment roster by another 1.4%. And the service there sucks too. Why? The wages are so low that workers aren't motivated to give a shit about the company. Meanwhile Costco's employees get paid a living wage and their stores are far more efficient with better rated service.
