i think that there isn't enough competition. So many brands are owned by the same corps, supply chains vertical, largely same grocery store products/brands in Virginia as California. You can't just raise prices unless you have leverage over competition.
This administration's pro trust busting is the start of a change i hope. Efficient capitalism needs competition more than it needs efficiency of scale. The sad thing IMO is thatnsocial spending at the bottom is being used as a scapegoat, when increased demand wasn't the biggest player.
