you can't compare this. Walmart is huge and probably has, in some areas, some kind of monopoly. If you sell your stuff on a flea market, I can deal with you to get a price that suits both of us. You have competition all around you, easy to reach, easy to compare. You are selling umbrellas, Walmart is selling water, one of if not the most basic food, for a maximum profit. The additional profit goes straight into your pocket. Same for Walmart, it's not like the employees somehow benefit from a price raise. Yes, the free market works like that: demand and offer control the price. But at some point this reaches the area of immorality.
