Large grocery store chains have very small profit margins. For example Kroger, which is the largest in the USA had a profit margin of 1.4%. Apple had 22% profit. There no room to trim when it comes to grocery stores, unless the goal is drive them into bankruptcy. Harris is clueless. A grocery store has thousand of items from hundreds of venders, and there are many layers of middle men, from farm to grocery shell for each item. Any place you price fix, can gum up all the works. We do not need an emotional thinker, tinkering with the economy, since that is why we are in this mess. Keep Harris away from the economy since she is clueless and panders to the clueless.
Trump idea begins with getting the price of oil to drop by drilling and increasing supply. The opposite action by the DNC has led to the mess we are in. The more oil supply we have, the lower the price. Every step of every product, from farm to grocery shelf, uses oil in same shape or form, such as to make electricity or run a tractor or delivery truck. With oil cheaper, everything comes down a little at each spot, until the consumer feels the price decrease. The consumer also saves money if gas and electricity go down, so they have more money to spend on lower prices, which then makes new business want to open and compete which increases supply, price falls even more and wage increase due to more need for employees.
That one action of lower gas prices is a positive trigger for prices to come down. Lowering regulation is also useful. There are many Agencies that are corrupt and compromised adding to the cost of business. As an example, there was a Supreme Court case, connect to the rise in sea food prices. A somewhat new regulation required all fishermen boat owners pay to have an EPA agent on board to over see their fishing. The boat owner is forced to pay the DEI salary for another employee who did not work, which increases their cost, due to the extortion. The fisherman won their case. Some agencies use law fare against political opponents which does not help anyone but themselves.
Another Supreme court case challenged the authority of any agency to make laws, since only Congress can do that. The agencies has made laws for their own growth; red tape for unions to add more employees, and not the best interests of the American people. Government is very often the source of many economic problems.
