You want me to write a dissertation on why Capitalism doesn't provide reasonable prices, cannot provide "actual robust competition", and cannot stop a few big monopolies?. Sorry, I'm not going to. Lenin was writing about this stuff 100 years ago.. The current state of Capitalism, that is Capitalism. That's how it functions. There isn't some idyllic form of Capitalism that we can work towards ... that has never existed ever.

People like to point to the 1950s and 1960s postwar US and the Nordics as examples of "how Capitalism should function". Postwar US was in a red scare, Communism spreading across Europe, fear of uprisings at home, and that fear forced progressive concessions. The one era of capitalism people romanticize is that one, and it was shaped by fear of Communism plus massive grassroots working-class movements.

Same thing in the Nordics. What is right next door? The Soviet Union, with a successful revolution that brought millions out of abject poverty and brought USSR from a feudal backwater to modern superpower within decades. The fear of that spreading caused Nordics and elsewhere to give more concessions to the working class. The form of Capitalism itself hasn't changed one single bit. There's still wars, worker exploitation, imperialism, global extraction and exploitation of the 3rd world (global south), etc.
