The issue is that the prices of staples have also been increasing precipitously an there have been clear cases where prices have risen universally across suppliers in a 'why leave money on the table, our competitors have raised prices, let's match them' type of way. Something does need to be done about that type of situation; in a properly working free market the competitor would gleefully accept having 100% of the market and waiting for the high price supplier to go bankrupt or lower their prices. Instead you're seeing what appears to be cartel-like 'we've got your back' from suppliers. This was most recently visible with eggs.
