Conservatives will say it's a significant and important job creator.
The evidence shows otherwise, according to Kathleen Geier:
It does this by putting local small stores out of business and forces suppliers to cut costs that in many cases leave them no option but to shed local jobs or relocate manufacturing overseas.Contrary to Walmart’s self-glorifying mythology, the retailer is anything but a job creator — in fact it is a huge job killer. Not only that, destroying jobs is an essential component of Walmart’s anti-worker business model.
And of course any productivity gains do not go to the remaining workers.
http://www.salon.com/2013/08/05/walm...t_create_jobs/Some of Walmart’s defenders explicitly defend its brand of low-road capitalism. They celebrate it as productivity-generating “creative destruction.” Indeed, if you produce the same level of output using fewer labor inputs, you will by definition increase productivity. In theory, this is terrific, since gains from productivity can be shared, making us all richer. But in practice, this hasn’t been happening. Between 1973 and 2011, productivity soared, increasing by 80 percent, but compensation for the median worker increased by only 11 percent.
