I think you don’t have a good definition of capitalism. Let us define it as a system where a small group of individuals (capitalists) control the means of production, and everyone else (workers) creates value, most of which they don’t receive… That in itself has nothing to do with corruption. It has nothing to do with stagnation.

And the examples you gave were about innovation, and innovation happens in many non-capitalist systems, too. No reason socialists can’t innovate, is there?

But what we also see is that capitalists hate capitalism. They have to compete, they could lose. So invariably they try to seize power in other ways. Therefore, one could argue (and many have argued) that capitalism leads to (or is likely to lead to) fascism.

At the same time, understand that any system can be corrupted. Some are less stable than others, but we always need to keep an eye out for the shady selfish jerks.
