Vendors are not out there for fun, they sell goods for profit.
Price caps on groceries will result in either the companies hiding profits upstream; or food shortages. We don’t need feel good economics policies that do nothing at best and harm at worst.
This is irresponsibly dangerous policy. The socialist response to market failure should be providing a government alternative for food distribution if the market fails. To heavily fine and break up or disband the companies which cheat and steal.
We deserve better, do better
