>> the idea that firms are capitalizing on their market power by raising their prices higher and faster than the growth in their production costs.
You think this is a plausible explanation in a competitive capitalist economy rather than the problem being trillions of dollars having been printed which devalues all money which makes prices go up which makes the corporations look like they made record profits because you HAVE to charge more money because all money is worth less and every input costs more? I'm not saying they didn't necessarily make record profits, btw, but if they did then good on them and that smells like a blood in the water type of business opportunity.
