Who doesn't want more for their money? Innovating and designing CPUs isn't the easiest task in the world and as transistors get smaller and smaller the cost goes up for the manufacturing equipment to make those itty bitty transistors. Cost will naturally increase as well to cover the R&D and manufacturing costs until someone discovers a break through that changes how we do CPUs and lowers the costs to develop ever more powerful processing units. Also, with the imminent release of of Rocket Lake chips, there could be enough competitiveness that AMD may lower their prices to keep selling their chips as fast as they can make them.
The cost of building new chips keeps rising every node -- so much so that by 3nm, there might be precious few companies that can afford new chips at all.

If you don't like monopolies then you need to suck it up and buy AMD at the prices they are asking as they are far behind overtaking the Intelopoly. To buy Intel at the moment is supporting a monopoly, though a weakening one.
