Walmart tonight, is it pure evil, Robin Hood, or both?

Here in this agricultural fruit growing region, the store was filled almost entirely with those who are native to America, South at least and maybe some from the north. The shopping carts full of food, toys, and other products. A very nice store. Very very fair pricing even competitive with Amazon probably.
Who else is serving the underclass in this country as well as Walmart? Nearly as well as Walmart?
Walmart is a robber to do this and the Walton family obscenely wealthy , no excuse.
But are they not robbing from Middleclass America and serving the underclass? How is that fundamentally different than what Robinhood did?
The Republicans certainly would never provide such service to the underclass, any more than would the Democrats. And the middle class never did, they to robbed, but from the poor. And still do.
