Of course it's a win-win. The money those low net worth households save doesn't disappear: The poor spend most of their income, and as a result, the money that was going to a more inefficiently manufactured product is now being spent on something more economically competitive. A burrito at Chipotle or a pair of sneakers or an Android phone.
Nobody's entitled to a job, but when Walmart trims inefficiencies, it ensures that consumer spending is going towards the products of more efficient producers at their own stores and elsewhere, adding jobs where they can be the most productive.
