Earlier quoted context omitted.
Suppose the government did put its thumb on the scale here, how would it impact consumers? Will they now be able to shop for lower prices at a business that earns 1% profit margin or less instead of the 2.6% profit margin that Costco has managed to climb to?
The government is not supposed to be in the favoritism business. When that happens, as we're seeing, there are unexpected and/or unwanted consequences. The government is supposed to level the playing field, not the other way around.
Technology and economies of scale favor Costco, and Walmart and etc. And people obviously like the low prices due to the economies of scale.
